Top 10 Worst Movies Based on Cartoons

The Top Ten
1 The Last Airbender

I'm honestly not bothered too much by the skin color that everyone else bashed the film for, but there are many other issues. Awful acting, designs that look nothing like the originals, random pronunciation changes, surprisingly cheap-looking visuals, boring action, no emotion or character, incredibly bad acting (the guy who plays Zhao was once the pizza man in Spider-Man 2, where he was good), and a few other things that really bother me.

The main things need more discussing. First of all, the pacing is the worst of any film I've ever seen. They spend half the movie on 18 of the 20 episodes, cutting out important characters like Suki, Bumi, Jet, Teo, and the Cabbage Man (who is not necessary but also appears in later seasons like the other characters). The fact that Agni Kai, the winter solstice, and the storm are left out is stunning because these are great moments that define the show. Instead, all information gained from those scenes is just spoken in out-of-order exposition. They even forget to mention Aang's name when they meet him and never even say Haru's name. They scarcely mention Ba Sing Se and Avatar Roku.

The second half, however, focuses on the other 2 episodes and is nearly the length of them, but it's still slow. The strong gender equality message is left out, Sokka and Yue have no chemistry, and the final battle leaves out all of the emotional moments. For example, one of my favorite moments in the show is when Zhao is grabbed by Aang in spirit form, Zuko offers his hand, and Zhao pulls away, choosing to die instead of letting Zuko, his rival, save him. Instead, Zuko leaves, and random benders drown Zhao in a bubble before dropping his corpse 30 feet to the ground. This film sucks.

While cutting out stuff sucks, my true least favorite part of this film is the random changes to the basics of the show. For example, people in the show now speak to each other differently from in the movie. There are many other random changes, but... more

2 Dragonball: Evolution

If someone's mother, who listened to her kid watching cartoons in the other room, wrote a movie, this would be it.

WatchMojo did a list called "Top 10 Ways Dragonball Evolution Got Everything Wrong." That's how bad it is.

I hate this movie.

This movie also deserves to be on the list.

I give it a skip over Mr. Magoo, which is a meh film.

3 Alvin and the Chipmunks

This movie is just a shameless cash-in, filled with terrible CGI, corny jokes, endless pop cultural references getting shoved down our throats, and unnecessary fart jokes to top it all off. Not to mention it wasted very talented actors, and our protagonist cares more about stupidity rather than David. Definitely stick to the 1983 cartoon instead of this one. I'm not a huge fan of the cartoon, but at least it wasn't this pandering.

I love the original 80s cartoon of the same name, but this movie is torture to sit through.

Imagine seeing this in the cinema and having to endure the annoying high-pitched voices of the chipmunks. What a nightmare!

Also, that one joke with Simon eating Theodore's feces... Why? Just... Why?

4 Mr. Magoo

This is my least favorite movie based on one of my favorite cartoons ever made.

This makes the live-action Scooby-Doo look like George of the Jungle!

5 The Smurfs
6 Masters of the Universe

Did you grow up watching He-Man? Did you ever imagine that his feature film adaptation would transport him and his friends to California? Neither did we.

7 Alvin and the Chipmunks: Chipwrecked

The first two were much better than this garbage. They didn't follow much of a plot and basically sang pop songs the whole time.

They just farted! Isn't that funny?

8 A Fairly Odd Summer

No one likes these movies. Nick is just making them when they get bored. Why? You have a ton of other shows to make movies from, and they're just continuing to make these godawful Fairly OddParents movies.

It would be perfectly fine if they were animated. It would probably get some people watching, but no, they just make these stupid live-action movies with horrible CGI fairies that no one watches. Also, the casting is really crappy. Drake Bell has always acted like he's just phoning it in when he does these movies. Trina from Victorious has proven in these movies that she is one of the worst actresses of this decade. Cosmo in these movies sounds like he's trying to irritate you. Wanda is just like she has been in the show since Poof came along, the fun killer. Poof is still the godawfully annoying abomination that has been in every episode since Fairly OddBaby.

Jorgen is the worst-looking fairy in these movies. He looks so fake. Granted, so do the others, but he is the worst looking of them all. These movies need to stop being made because no one watches them, and they're just awful wastes of time.

9 Jem and the Holograms

Just when you thought there would never be an adaptation worse than Last Airbender, along comes this. Even if you're like me and you've never seen the show, this movie is still horrible. It took a sort of sci-fi musical cartoon and completely grounded it in reality. Why the hell would you do that!?! It's like making a live-action Danny Phantom movie, completely removing the ghost stuff, and just having him dress up in the black suit and put on a grey wig, and he just goes out fighting other people dressed up as ghosts.

And what did they do to Synergy? Why would you take a gigantic supercomputer and make it look like some kind of Eve knock-off? And why did they have to keep cutting to all those pointless YouTube videos? It was incredibly annoying. Also, why did they modernize the movie? What Jem fan would ever in a million years want to see all the characters talking about Twitter or Instagram?

But you wanna know what the worst part about this movie is? The ending. Before the movie was done, they asked a bunch of classic Jem fans if they wanted to be in the movie. All they had to do was make a video saying how much they love the original cartoon. BUT, the editors of the movie then took all those videos and tried to edit them to make it look like they're talking about the movie. WOW! That is downright cruel! It's so bad that it's still hard to comprehend. That's like having a bunch of DragonBall Z fans make a video saying how much they love the original cartoon and editing it to look like they're talking about Dragonball Evolution. That is just insulting.

And the edit is so bad that it's clear they're talking about the cartoon, not the movie. They're dressed like the characters from the cartoon and they have the cartoon playing in the background. It's so clear that they're not talking about the movie that it just makes the sequence look even more pathetic. Move over Last Airbender, we have the new crowning jewel of crappy live-action movies based... more

10 Scooby-Doo: The Movie

I remember watching this at a young age at a family party and hating it. Looking back at it now, I can see why. The only memorable scene is the "Are you challenging me?" bit, but the only reason that's memorable is for the memes. Also, Matt Lillard's performance as Shaggy is great.

Those don't make up for the cruddy CGI, dumb story, flat characters, and poor humor. Hopefully, the upcoming Scoob movie treats the character better.

The guy they got to play Shaggy was the only good casting in this movie. The rest of the people they got to play the other characters were downright horrible. Also, some really crappy CGI. I mean, come on, Superman 4 had better effects than this! Even by early 2000s standards, they were bad.

Also, what was up with those creatures? The Scooby-Doo TV shows made it clear that there's no such thing as supernatural elements in their world. Every monster had a scientific explanation. But for some reason, not here. They're just real monsters that pop out of nowhere and suck out people's souls. What the hell is this movie at that point?

The Contenders
11 Teen Titans Go! to the Movies
12 Inspector Gadget

I have so many things to explain how bad this movie is. This used to be one of my guilty pleasures, but I found it flat out ridiculous. It's almost nice to see Dr. Claw's face, even though he never showed it in the cartoon, but too bad, everything about him stinks. I mean, his scary voice is replaced with a snooty British accent. And besides, he has a robot claw on his hand in the movie. After he gets it, he renames himself "Claw." Wait, shouldn't "Claw" be his last name? According to the cartoon, his real name is George Claw, right? Well, in the movie, his real name is Sanford Scolex. Why not just rename himself Dr. Claw? The actor Rupert Everett did a terrible performance as Dr. Claw overall.

The Gadgetmobile is changed from a silent car, which morphs into a sports fastback and van in the cartoon, into an annoying comic relief character in the movie. Penny isn't blonde and she barely helps Gadget. You know who did a good job at playing Inspector Gadget? Don Adams and Maurice LaMarche were good actors to play him, but Matthew Broderick is not. Like Rupert Everett, Matthew Broderick did a terrible performance on his character. Both Gadget and Dr. Claw behave nothing like their cartoon counterparts.

Every time Gadget falls in the climax, he says "Go Go Gadget," which gets really annoying. Some scenes make no sense, like Gadget saying "Go Go Gadget Oil Slick," but he shoots toothpaste instead. Every single second of the movie, cartoon sound effects are heard, even though this movie is based on a cartoon. Sometimes, the movie can be really disturbing for younger audiences, like when Gadget grabs a guru by the crotch so hard that the tightness of the squeezing makes his eye pop out to a really big size as he yells in a very shrill, extremely high-pitched Judge Doom-like shrieking voice. You'll be hearing that when you sleep in the middle of the night. No, don't waste your time on this movie. It will give you nightmares because of that disturbing scene I... more

13 Alvin & The Chipmunks: The Squeakquel

The worst Alvin and the Chipmunks movie.

14 Underdog
15 Bratz: The Movie

This whole movie is like if Mean Girls was made by someone less talented than Tommy Wiseau.

This one needs to be Number 1! It's worse than The Last Airbender and Mr. Magoo!

This is a big insult to teenage girls everywhere!

16 The Flintstones

What I really don't understand is how Barney got the highest score on the test. I've seen a few episodes of The Flintstones, so I know the characters, and Barney would clearly not be the smartest guy there.

Sucks like crap. It should be number 1 on the list!

This movie isn't that good, but I think Viva Rock Vegas is probably worse. Yabba-dabba... don't!

17 The Smurfs 2
18 A Fairly Odd Movie: Grow Up, Timmy Turner

This movie is just stupid and forgettable!

19 Death Note
20 The Adventures of Rocky and Bullwinkle

This is one of the more "not bad but not good either" movies I watched. I can tell that most of the production tried, except for the actors. They're bad. But it has the charm of the original and is not the worst movie based on a live-action cartoon. "Cough" Dragon Ball and Last Airbender "cough."

I hated Fearless Leader, Boris Badenov, and Natasha Fatale so much. They were jerks to Rocky and Bullwinkle.

21 Transformers: Revenge of the Fallen

Sorry, but this movie destroyed the franchise. The movies should have been based more on the show.

Love it, love it, want more of it, but it's unwatchable.

22 Boris and Natasha
23 Inspector Gadget 2

A little better than the first one but still kind of bad. At least Gadget is a lot more incompetent here.

24 The Flintstones in Viva Rock Vegas

Even though this movie seriously reaches the mark of what is considered to be the worst movie based on a cartoon, it still reaches it. The main problem is how predictable and been-there-done-that both the story and characters are. I predicted who the villain was, what the twists were, and even how it was going to end.

Also, Fred's "stupidity" didn't affect me at all because I knew he wasn't doing it. The fact that the writers thought they would fool me is irritating. I've heard people talk about dealing with loss being the central theme of the movie, but maybe if the movie put more logic into it, I would actually care.

25 Tom and Jerry: The Movie

I agree with people who voted on this one. They basically ruined the entire idea of Tom and Jerry: Tom chasing Jerry. Instead, this film makes them allies just because they speak. I have to admit, the fact that they find out they talk was pretty funny, but making them allies in barely any time at all? God, and then there's that part about the young girl that Tom and Jerry meet and help her escape from her abusive guardian. Say what!? This is basically the Disney film The Rescuers in some sort of nutshell. Only you add in one of the most popular cartoon duos, add a bunch of forgettable songs and annoying new characters, and make the plot completely garbage.

What the heck were the writers thinking? They didn't even add in Spike or Tyke the dogs! Moral of the review: This movie will torture Tom and Jerry fans, even the younger ones.
