For eight seasons now, AMC's zombie-thriller show The Walking Dead has been must-watch viewing for horror and sci-fi fans everywhere. Watching Rick and his fellow survivors navigate a world which has been ravaged by Walkers has been exciting at the best of times, not to mention tense! We've seen much-loved characters succumb to the zombies, others betray their loved ones, and some even attack each other in rage or jealousy. It's certainly been a rollercoaster of emotions — and it looks to be getting even more dramatic in the near future, with CBS News reporting that Rick actor Andrew Lincoln will be leaving the show in the next season. Where will the show go without its lead character? We'll have to wait and see!
Of course, even the best-loved shows of all time have their flaws. Over the years, there has been a heck of a lot of things that The Walking Dead have got wrong! Plot holes have been left open, characters have made totally nonsensical decisions, and some pretty unrealistic twists and turns have taken place. Sure, a show about zombies isn't necessarily going to be teeming with realism, but some mistakes just aren't forgivable! Here are just some of the times that The Walking Dead made absolutely no sense to dedicated fans and casual viewers alike.
22 How Did Rick Even Survive His Coma?
In the very first episode of The Walking Dead, lead character Rick Grimes gets a bit of a shock, to say the least. As told on ZombiePit.com, he wakes up from a coma to discover that the world has been overrun by Walkers, including the hospital in which he's been staying. Obviously, Rick's first task is to get the heck out of there and find his wife and child.
Things don't exactly go to plan, though... And the rest, as they say, is history!
However, there are many fans out there who believe that Rick shouldn't have survived this first episode at all — and we're not just talking about the scene in the tank. In reality, it makes very little sense that Rick would have woken up from his coma. Unless he hasn't, and all of the events of The Walking Dead are a dream! It seems unlikely, since, according to ComicBook.com, the show's creator Robert Kirkman has openly debunked that theory...
Anyway! Considering the hospital that was treating Rick had been taken over by zombies, it's very unlikely that he'd have survived his coma. There were no doctors there to treat him anymore, and there were plenty of Walkers around who would have loved to eat his brains. How could anyone survive those circumstances?
21 Glenn's Unbelievable Resurrection Made Very Little Sense
Speaking of characters who managed to stay alive against pretty much impossible odds... How did Glenn survive the Walker attack in Season Six? The hiding under the dumpster explanation was just so lame! As The Independent noted prior to the character's actual passing, Glenn was pretty much the luckiest survivor in the entire show for many seasons. He came close to losing his life so many times, but always managed to cling on. He was a great character, so nobody really minded that he had insanely good luck... Until the dumpster incident. Like, seriously. He should have been eaten by zombies!
For anyone who missed out on that storyline at the time, just know that Forbes declared it the one thing that "completely screwed up" Glenn's time on the show. Apparently, in the midst of an attack from dozens and dozens of ravenous Walkers, Glenn managed to hide underneath a dumpster and escape totally unscathed. We're sorry, but no. Even if some of the Walkers were preoccupied with feasting on Nicholas, are we supposed to believe that not one of them noticed there was another very alive dude right there? From this moment on, Glenn really was living on borrowed time — and eventually, his maker came in the form of Negan.
20 Why Does Anyone Still See Rick As A Good Leader?
Here's a question for all of the Walking Dead aficionados out there: why have many of the survivors continued to follow Rick even though he's a kinda terrible leader? Don't get us wrong, we love the guy, but you've got to admit that many of his plans have backfired spectacularly. As CinemaBlend notes, he's got one major quality that puts himself and his comrades in the path of danger again and again: he's way too impulsive! We don't know if Rick has a hero complex or just enjoys the feeling of his life being at risk, but he does seem to go after various bad guys and mysterious happenings without considering the danger involved. He needs to think things through a bit more!
Now, this point may be a bit controversial, but hear us out, okay?
Another thing that does sometimes compromise Rick's leadership abilities is the fact that he loves his children so much.
We know, we know — that's hardly a bad thing, and you can't really blame him. In the face of danger, any parent's first instinct is to protect their brood. However, you've got to wonder if sometimes, Rick's put the needs of the few — himself and his kids — above those of the wider survivors group. Sometimes, a leader needs to make tough decisions to make sure as many people as possible survive — even if that means putting his own family in danger. Rick has always been totally unable to make that sacrifice.
19 Many Characters Have Somehow Maintained Their Grooming Habits In The Middle Of An Apocalypse
This particular nonsensical aspect of The Walking Dead may not affect the plot too much, but it does still kinda bother us. How do so many of the characters maintain perfect grooming habits in the middle of a zombie apocalypse? We're talking precisely shaped facial hair, plenty of trimmed hairdos and, most worryingly, the fact that every female character somehow has shaved armpits. As The Huffington Post notes, that's not just unrealistic — it's just plain sexist. Is female body hair so unacceptable that it still has to be removed in the middle of an actual zombie apocalypse?
Less offensive but equally as confusing is how exactly Simon managed to keep his handlebar mustache looking so perfect for so many seasons. According to CinemaBlend, even the character's actor, Steven Ogg, felt that this was totally unrealistic! He told CinemaBlend that he's "often amazed at that world, how everyone is so deliciously coifed." He went on to admit that he'd love to see Simon "have his head shaved and his mustache gone!" Sadly, this never came to pass — the character met a pretty grim end in Season Eight. Still, according to The Daily Star, one of the first things Ogg did after leaving the show was to get rid of his character's iconic facial hair! Can you blame him, really?
18 Years Into The Zombie Attack, People Are STILL Getting Bitten
At the very beginning of the zombie apocalypse, we could understand why so many characters on The Walking Dead kept on getting bitten by the Walkers. This army of undead creatures was a new threat, one that they hadn't yet learned how to deal with, and mostly just incredibly terrifying. However, over the years the few survivors scattered across the world learned how to fight the Walkers - and how to avoid attracting their attention.
You'd think that after a while, these guys would have learned how to totally avoid becoming victims of the zombie hordes... Right?
Well, apparently not. Years in, people are still falling victim to the Walkers, despite all of the defense mechanisms they've developed against them. As Metro reported last year, even high-profile characters are still being bumped off in this manner: Rick's son, Carl, was a particularly tragic example of this. But, seriously - would the son of one of the most prominent Walker-fighters out there really end up in a position where he could get bitten? Surely he, out of everyone left, would know what to do to avoid this fate? Clearly not. We're not sure we buy it, to be honest. If the writers wanted to get rid of Carl, they could have done it in so many different, more exciting ways!
17 Seasons Don't Seem To Happen In Atlanta Anymore
The Walking Dead has been going for a pretty long time now - both in terms of the number of seasons and episodes that have aired, and in how much time has elapsed in the events of the show. Years have gone by in the zombie-ravaged alternate Earth that the show's characters inhabit — just look at how much Carl grew up over the years! However, despite the Earth making quite a few trips around the sun as the events of The Walking Dead have transpired, Atlanta and its surrounding area seem to have been trapped in a permanent summer. We've never seen anything except this particular season: no autumn leaves, no winter snowfall, no blossoms of spring.
As Insider notes, there's a pretty practical explanation for this lack of diversity in the show's climate. Each year, the show is filmed in the summer and early autumn, meaning this is the season that's captured. There simply isn't any snow around when The Walking Dead is shot! However, you'd think that the show's creators could have dealt with this massive continuity error somehow. Like, not every TV show that takes place in the winter is filmed in the winter! Couldn't they have added fake snow to their shooting locations, or added the hallmarks of different seasons afterward using CGI? Just a thought!
16 The Problem Of Hershel's Missing Leg Is Solved Way Too Easily
Poor Hershel Greene didn't exactly have the best time of things during his The Walking Dead run. This elderly mentor to Rick lost a leg to the Walkers in Season Three, before perishing at the brutal hands of the Governor a mere season later. Rolling Stone described Hershel's initial Walker attack as one of the grossest moments in The Walking Dead's third season, and we can see why. Not only was the Walker-attack itself pretty terrible to watch, having to see Rick remove Hershel's infected leg was fairly terrible.
Still, it added an extra layer of depth to the character: how would he cope being an amputee? Would it affect his ability to deal with the zombie threat?
As it happens, we didn't have to find out the answer to either of these questions. As CinemaBlend notes, when Season Four began, Hershel magically seemed to have a leg again. He was walking around as usual without a care in the world! It's later revealed that he's wearing a prosthetic leg that was simply found somewhere in the prison. Did somebody say "ridiculously easy resolution"? Why would there just be a replacement leg lying around somewhere, and what are the odds that one of the survivors would actually find it? Pretty slim, if you ask me! Plus, learning to use a prosthetic is by no means easy: it takes a lot of getting used to. How come Hershel seems to have no problem using it from the outset?
15 The Use Of Guns Is Just Totally Unrealistic
Now, before you say "of course there are plenty of guns in America", hear us out. It's not just the fact that everyone magically seems to get guns at one point in The Walking Dead that's the problem here — although it is a bit weird. As TV Guide notes, the show's character seems to go through gun and ammunition shortages only when the plot requires it — otherwise, there are just weapons everywhere.
For example, near the start of the show, guns are so rare that people will actually attack other people in order to get hold of them. However, there seems to be unlimited ammo — people just going around shooting their few guns willy-nilly. Later in the show, there's a legitimate ammunition shortage — but a season later, people are back to not giving a second thought to using dozens of bullets at once. What gives?
Then there's the fact that The Walking Dead's firearms department doesn't seem to actually know how firing a weapon works. As Forbes notes, characters can shoot weapons without any of the real-life complications: there's no recoil, for example, and bullets reload way quicker than they would in real life. Sure, it's not the biggest problem The Walking Dead has, but it still gives the show a faker feeling than it needs.
14 How Do The Walkers Still Have A Sense Of Smell?
One of the most dangerous aspects of The Walking Dead's zombies is their heightened sense of smell. The Walkers can actually recognize the scent of a human, meaning they know exactly where to go to find their prey. It makes things a lot more difficult for the survivors: there are very few ways to get rid of their "human" smell, meaning they always have to be on the lookout for approaching Walkers. What a bummer!
However, many viewers of the show have questioned how exactly the Walkers can still have a sense of smell, despite essentially being dead creatures. For one, if they're pretty much brain dead, how are any of their senses still working? Secondly, what about the Walkers that don't actually have noses or nasal cavities anymore? There are plenty of them about the place!
Unless there's something seriously impressive going on with their anatomy, these zombies shouldn't be able to smell a thing.
The human survivors, on the other hand, most definitely should be able to smell the Walkers coming — but they seemingly never do. MTV spoke to two real-life doctors, who explained that the smell of rotting flesh and general death would be so bad in The Walking Dead's version of Earth, it'd be basically unbearable for anyone with a sense of smell. Plus, since the Walkers themselves are basically lumps of decaying human, they wouldn't smell too peachy either. They really don't have that much going for them. Poor things.
13 There Definitely Should Be Fewer Zombies Around By Now
While the initial phases of a zombie apocalypse would lead to a frighteningly huge amount of undead creatures inhabiting the Earth, many experts have suggested that this number would tail off after a while. According to Tor.com, even if 99% of the U.S. population had become Walkers in the initial plague of zombies, the remaining 3 million people would be able to defeat a pretty high number of these undead creatures. Buzzfeed breaks things down even further. Apparently, if every group of zombie apocalypse survivors took out just ten Walkers a month, there would be no zombies left within two years. Neat, huh?
However, this begs a very important question about The Walking Dead: why are there still hordes and hordes of zombies left? Despite the fact that dozens of Walkers have been bumped off since the show started, there still seem to be the exact same amount of these creatures out there. Huge crowds of zombies still appear from nowhere to attack our heroes, and after each battle, loads of them seem to magically regenerate. Sure, we know that the show would have been a bit less dramatic if the war against the Walkers had ended quickly... But seriously? Why are there still so many of them?! It doesn't make any sense!
12 A Product Placement Deal With Hyundai Meant That The Characters' SUV Was Invincible
Dozens and dozens of TV shows are culprits of blatantly obvious product placement. You'll notice that the camera suddenly zooms in on the particular brand of phone that a character is using, or they'll make a really big deal of visiting a particular very famous coffee chain. While you might have thought that the makers of The Walking Dead would avoid this kind of marketing — most material goods in the zombie-overrun world have become unimportant, after all — you couldn't be more wrong.
There was one particular piece of product placement that was so ridiculous, it basically became a meme amongst The Walking Dead's fans.
We speak, of course, of the infamous green Hyundai Tuscon.
This car kept Rick and the gang moving for years, helping them get away from many sticky situations. However, it also seemed to be pretty much invincible. This vehicle could go through anything — Walker attacks, a bumpy drive, a crash or two — and still come out looking pristine and unscathed. In most episodes, it also seemed to have been recently washed — a slightly unrealistic state of affairs in the middle of a disaster. Eventually, as Variety reported, the writers of The Walking Dead could no longer find a reason to use the car, so it exited the show. However, fans will never forget this ridiculously lucky vehicle.
11 The Way The "Zombie Virus" Apparently Works Makes No Sense
As any viewer of The Walking Dead knows, the Walker apocalypse was originally started with a virus — colloquially called the "Zombie Virus." The show hasn't yet revealed where this virus came from, but as Bustle notes, we do know some things about its pathology. Apparently, every single human is a carrier: however, the zombie transformation is only activated when a person passes away. The only way to prevent a corpse from becoming a Walker is to destroy its brain. A zombie bite doesn't actually cause or spread the virus — it only adds more of the virus into a bloodstream that's already infected with it.
However, a lot of these "facts" about the virus don't actually make much sense when you consider a lot of what happens in The Walking Dead. For one, why was Carl so devastated about getting a zombie bite when he actually already carried the virus anyway? Surely getting bitten would have had no effect on him — but it apparently hastened his death. How does that work? Plus, as Bloody Disgusting notes, there's the fact that Gabriel was able to "save" himself from the virus using antibiotics, but this wasn't an option for Carl. What??? Also, how was the virus able to turn Gabriel blind? The writers have really tied themselves in knots here...
10 Why Is There So Much Conflict Between The Human Characters When The Zombies Are Clearly The Real Issue?
Across all eight seasons of The Walking Dead, it's become abundantly clear that the characters in this show have never heard of the word "priorities". Despite the fact that they're desperately trying to survive an ACTUAL ZOMBIE APOCALYPSE, the survivors seem to care more about their own internal strife and rivalries than the huge disaster that threatens their lives every day.
Like, seriously, guys — surely domestic disputes can take a back seat at a time like this! Can't you save all of your arguments for a time when the Walkers have been defeated?
This is a topic that was heavily discussed on StackExchange's Sci-Fi section, and fans have come up with a number of explanations. Some are still baffled that this infighting takes place, and believe that the characters should be shown working together a bit more. Others state that these conflicts are simply human nature, and can't be avoided. A final possibility is that in a world where there's no clear leader left, violence is going to ensue as various people set their sights on getting the power to lead and control others. As much as some fans might want The Walking Dead to be more about the zombies and less about the nature of the human psyche when we're put under stress, it doesn't seem like that'll happen any time soon!
9 The Governor's Missing Eye Has Raised Some Questions
One of the most distinctive physical characteristics of David Morrisey's The Governor was the eye patch that he wore over his right eye. Or is it his left? Well, at one point, it seemed like The Walking Dead couldn't quite decide which side the patch sat on. As ComicBook.com notes, eagle-eyed fans of the show spotted a pretty major continuity error in the third season episode "I Ain't A Judas." It's the episode in which the Governor takes off his patch to reveal the scarred eyesocket that lives underneath it. Pretty gross, right?
Well, fans weren't paying attention to just how painful this wound looked. Actually, they picked up on the fact that it was the character's left eye socket that seemed to be damaged when he usually wears the patch on his right side. That's right: The Walking Dead actually managed to mess up which eye one of its characters had lost. How do you even make that mistake? Did the makeup and prosthetics department not check repeatedly that they were applying gory effects to the correct side of David Morrisey's face? It seems like a pretty huge gaffe to make it past the show's producers... Except actually, it wasn't a gaffe at all. Turns out The Governor was looking into a mirror when he showed off the socket. You'd think the show would have made that clearer...
8 The Whole Sophia Debacle Had Many Fans Totally Stumped
Oh, Sophia. That little girl caused so much stress and drama in The Walking Dead's first and second seasons. She was the daughter of Carol, one of the initial survivors of the zombie attack, but was separated from the main group during a Walker attack. Rick had instructed the young girl to wait by a creek while he dealt with some zombies, but by the time he and his fellow survivors had returned, she was gone. This, of course, led to a huge search for Sophia, which ended in tragedy. It turned out that the Walkers had got her, and she was one of the creatures living in Hershel's so-called "Walker Barn". Rick had to destroy Sophia's brain, a necessary but traumatic act.
While this storyline was more tragic than anything, it also left a lot of fans confused.
As Headline Planet noted, a lot of people questioned why Hershel didn't mention to the others that Walker Sophia was living in his barn. Did he just not notice that the distinctive small child that everyone was looking for was in there? Did he know, but not want to break the tragic news to Sophia's family? We're still not entirely sure what Hershel did or didn't know, and it doesn't look like we'll ever find out.
7 The Walkers' Abilities Seem To Vary From Season To Season
Question: does anyone actually know what the Walkers can and can't do? In fact, are the writers of The Walking Dead actually sure about this? It would seem not, based on the zombies' varying capabilities as the show has progressed. As TheThings notes, a lot of Walking Dead fans actually think that the Walkers have got stupider and stupider as each season of the show has passed. Not that the zombies were ever geniuses by any means, but yeah — they definitely seem dumber now than they did in Season One.
For starters, the Walkers' methods for catching their human prey seems to have got more and more simplistic as each season has passed. While previously they could open doors and act in a slightly human-like manner, now all they can do is swarm and grab at people. They could use objects to help themselves along — using rocks to break windows, for example — and could climb things to get to people. These days, they're basically rooted to the ground. It's like the Walkers have suddenly become really, really lazy, and only try to attack people who they can access with ease. It makes them slightly less threatening, you've got to admit. All people need to do is go into the second floor of a house, and the Walkers are apparently unable to reach them. Go figure.
6 Why Are There Seemingly No Animals Left Following The Zombie Apocalypse?
Another major mystery in the world of The Walking Dead is where exactly all of the world's animals have gone. We've barely glimpsed any critters at all throughout the entirety of the show, which is an oversight of massive proportions. How awesome would it be if the survivors suddenly had to deal with some zombie bears or wolves, or escaped zombie zoo animals? Even on a day-to-day basis, it would be kinda creepy to see zombie squirrels running around the place.
However, the show has apparently decided to ignore this possibility entirely, and it totally stinks.
In the past, The Walking Dead's creator, Robert Kirkman, has actually addressed the lack of zombie animals. According to The Huffington Post, Kirkman told Conan O'Brien that it's all down to the personal preferences of Charlie Adlard, the illustrator of the original Walking Dead comic books! Apparently, Adlard doesn't like drawing animals very much, so he simply didn't. There's no huge plot reason for no animals being around: it's not that the Zombie Virus destroyed them all, or they all went into hiding somewhere to avoid the Walkers. It's literally just because one guy decided not to draw them. Looks like The Walking Dead's fans read way too much into this!
5 Who Mowed The Lawn In That Darn Prison?
This may have only been a minor Walking Dead inconsistency, but it still irritated legions of fans. Who on earth mowed the lawn in the prison that the survivors stumbled across? For anyone who can't recall this particular storyline, the prison in question is the West Georgia Correctional Facility, and the survivors spend a lot of Seasons Three and Four living there. When they first find the prison, it's been quite some time since the zombie apocalypse began — you'd expect it to be in a state of total ruin. However, much to the chagrin of viewers, the prison's lawn was shown to be perfectly mowed.
As Hollywood.com notes, one of the many remaining mysteries on The Walking Dead is who bothered to cut that grass. Like, would that really be the first priority in the case of a Walker invasion — or a priority at all, in fact? Surely it's just a waste of power. Nobody needs a neat and tidy lawn at this point: they just need to survive. The show's producers may not have thought that this aesthetic choice would matter when they filmed the prison scenes, but they were wrong. Never underestimate the ability of TV show fans to pick up on one tiny mistake and make hundreds of memes out of it.
4 There Should Be Way More Food Available Than The Show Suggests
A common trope in disaster-themed TV shows and movies is there not being enough food to go around. The Walking Dead is no exception. As Uproxx notes, it got to the point a few seasons ago where some survivors were eating pigs that had themselves been fed bits and pieces of Walkers. You would only do that if you were truly desperate, right? There are many other references in the show to rationing, depleting food supplies, and people not being willing to share the small amounts of edible resources that they actually have.
Makes sense in the context of a major, country-wide disaster, right?
Well... Possibly not. Actually, there should be a fair bit of food to go around, if the survivors know where to find it.
Think about it: a pretty large portion of the human population has now become the Walker army.
These zombies don't need regular food to survive: they just eat brains and other human body parts instead. Therefore, sitting in grocery stores and abandoned fridges everywhere should be a ton of food — or at least enough to go around! It has to be one of the only good things about the zombie apocalypse, really: the human race now needs a lot less food in order to survive comfortably. This isn't even including them growing their own fruits and vegetables and raising their own livestock. These guys are totally fine!
3 Did Maggie Just Totally Forget About Her Beloved Sister?
The zombie apocalypse that's ravaged the world depicted in The Walking Dead has led to many families and loved ones becoming separated. Children have lost their parents, adults have lost their partners, and siblings have often been left unaware of their brother or sister's fate. Of course, a lot of the time the survivors have actively gone looking for their missing loved ones: think of Carol desperately searching for Sophia. However, others have seemingly totally forgotten about their friends and family, and have made no effort to find them whatsoever.
Falling into this second bracket is Maggie, whose sister Beth disappeared during Season Four. You'd think that Maggie would be pretty torn up about the unknown whereabouts of her teenage sibling, but for a long time, she didn't seem to care about the situation at all. As The Hollywood Reporter notes, even when Maggie found out that Beth had been taken by an unknown assailant, she doesn't make much of an effort to search for her.
When quizzed about this, Beth actress Emily Kinney suggested that her on-screen sister was too focused on staying alive to do any major looking for her missing relative — or so FandomFound claims. Considering these two seemed to be pretty close siblings at the start of the show, Maggie's lengthy inaction is pretty out of character. Not that it matters now, of course — poor Beth met a violent end in Season Five.
2 Zombie Guts Have Suddenly Become More Dangerous Than Before
One of The Walking Dead's most nonsensical plot holes of all time revolves around the guts and innards of the Walkers themselves, and what they can or can't do. As Insider notes, in Season Eight, much-loved character Gabriel falls ill with what turns out to be a mild infection. Eugene suggests to Gabriel that he may have picked up a minor version of the zombie virus by smearing himself in the creatures' guts. Later on, the apparent danger of these guts is highlighted again: as Digital Spy notes, all-around bad guy Negan smears his weapons in the stuff, apparently to make them even more deadly than before.
The evidence is conclusive: zombie guts are dangerous, and may even spread the virus.
However, as Digital Spy continues, this is actually a major continuity error. In previous seasons, various characters have happily covered themselves in zombie innards in order to avoid detection by the Walkers. Likewise, some people have been accidentally splashed with bits of a zombie during battles and the like without coming to any major harm. Why is it that in Season Eight, the Walkers' guts have suddenly become incredibly dangerous? Could it be that this has been retconned by the writers to suit their current storylines? Very possibly...
1 The Infamous Season Seven "Paper House" Incident Was Too Ridiculous For Words
Now, none of us here are so naive that we believe every single set and location in our favorite TV shows is CGI and editing-free. We know that green-screens exist, and that careful manipulation takes place to make a show's setting as close to the writers' vision as possible. We just don't realize it most of the time, because these tricks are cleverly concealed or painstakingly edited out. A lot of incredibly talented people work very hard to make sure that we viewers are treated to TV and cinematic magic — without a bit of green-screen creeping in the corner.
However, in Season Seven of The Walking Dead, eagle-eyed fans spotted that a pretty major editing error had apparently made it into the final cut of the show. As The Huffington Post reported, the house known as The Hilltop seemed to have an interior made out of paper! This inspired a hilarious Reddit meme, titled "When You Blow The Entire Budget On Zombies And Have To Use A Sheet Of Paper For The Inside Of A House." Some Redditors agreed that the house's interior was blatantly fake; others thought that maybe it was just bad lighting. Whatever the case, it's a gaffe that probably should have been spotted and fixed in post-production! Oops!
