Top 10 Worst Movies Based on Cartoons

The Top Ten
1 The Last Airbender The Last Airbender Product Image

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 even despite the skin 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 ...more

I haven't seen the whole movie. I have seen clips of it, and the acting is horrible. Also, this movie is racist because they choose white kids to play Asian-inspired roles. Also, the costumes are completely terrible and the characters look bad! Also, apparently Aang knocks Zuko away by doing some Karate moves. Lastly, the settings look nothing like they did in the original show.

I totally agree! This movie had SO MUCH potential! Why did you cast white actors as the characters when:
Air Benders-Tibetans
Water Benders-Alaskans/Inuits
Fire Benders-Japanese
Earth Benders-Chinese

Also, the tone. It was as FLAT as a pancake! No humor, no heart!

And what shocks me is that this was meant to be a franchise!

It doesn't matter if love or hate the show. This is a horrible movie either way. If you had not seen it your lucky cause you never had to feel the pain of watching this like I had so don't see it.

2 Dragonball: Evolution Dragonball: Evolution Product Image

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 of Mr. Magoo whiches a meh film.

Don't really care about Dragonball but Goku was cute.

3 Alvin and the Chipmunks Alvin and the Chipmunks Product Image

This movie is just a shameless cash-in, filled with terrible CG, corny jokes, endless pop cultural references getting shoved down our throats, and unnecessary fart jokes to top it all off. Not to mention it was 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'm really to any hip hop fan (and yes I'm the same guy who typed that comment on the led zeppelin song), but every rap song now today sounds the same. And when I mean the same I mean having no real message and just talking about drugs, money, sex, and violence. Most of these modern rappers never even been in the ghetto. Hip hop is dying and we need to do something about it.

I love the original 80s cartoon of the same name, but this movie is torture to sit through. Imagine seeing this in cinema and having to sit through the annoying high pitched voices of the chipmunks, what a nightmare! Also that one joke with Simon eating Theodore's feces, Why? Just... Why?

Annoying movie that shamelessly panders to kids using dumb poop humor and pop culture references? The amazing part is that this drivel got FOUR movies! HOW?

4 The Smurfs The Smurfs Product Image

Worst film of all time

5 Scooby-Doo: The Movie Scooby-Doo: The Movie Product Image

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 go 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 YOU! Even by early 2000's standards they were bad, also what was up with those creatures? The Scooby Doo T.V. shows made it clear that there's no such thing as supernatural elements in their world, every monster had a scientific explanation, BUUUT for some reason not here, they're just real monsters that just pop out of nowhere and suck out people's souls, what the hell is this movie at that point?

This movie wasn't bad. The casting was good, but I hope if they make a new one to spend more money on it so it would look better. Presentation is everything and these movies look a little cheaply made. Scooby Door is a great classic and when doing a movie it needs to succeed expectations that the cartoon does.

I liked the movie but it was also a gift for the haters of Scrappy who was totally out of character.
They made him evil just for the haters.

6 Mr. Magoo Mr. Magoo Product Image

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

7 Death Note Death Note Product Image
8 Inspector Gadget Inspector Gadget Product Image

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, because 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 on 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 as Inspector Gadget? Don Adams was a ...more

Rupert Everett was the worst possible choice for Dr. Claw to ever exist, and Mathew Brodrick was a horrible Inspector Gadget

Doctor claw never shows his face!

9 Teen Titans Go! to the Movies Teen Titans Go! to the Movies Product Image

I actually didn't think this movie was that bad. It was a lot like a kid's version of Deadpool, and in a good way. I was laughing out loud multiple times during this movie. The only bad qualities are the animation and the poop jokes.

Unlike the T.V. series, people think this is actually GOOD. Critics think it's good (it has a 90% score on Rotten Tomatoes), fans think it's good, people who hate the show think it's good. Maybe this movie might not be so bad after all.

10 Masters of the Universe Masters of the Universe Product Image

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.

Actually both the cartoon and movie are based on a toy line.

I haven't seen this but I bet its crap!...

The Contenders
11 Alvin and the Chipmunks: Chipwrecked Alvin and the Chipmunks: Chipwrecked Product Image

The first 2 were much better than this garbage. They didn't follow much plot, and basically sung pop songs the whole time.

They just farted! Isn't that funny?

Did not like this movie

12 A Fairly Odd Summer A Fairly Odd Summer Product Image

No one likes these movies, nick is just making them when they get bored, why? You have a crap ton of other shows to make movies off of and they're just continuing to make these godawful fairly odd parents movies, it would be perfectly fine if they were animated, it would probably get SOME people watching it, but no, they just make these stupid live action movies with horrible cgi fairies that no one watches, also some really crappy casting, 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 is in the show ever since poof came along, the fun killer, Poof is still the godawfully annoying abomination that has been in every episode since fairly odd baby. Jorgen is the worst looking fairy in these movies, he looks so fake, granted so do the others, but he is the worst ...more

Timmy Turner became a cgi fairy and he looks like his kid form and cosmo and Wanda will be with some spoiled rich kids... Let that sink in for a moment

In the show Timmy is 10 years old. Drake Bell is like 25! Timmy looks like a 25 year old!

One of the worst things I have ever seen.

13 Jem and the Holograms Jem and the Holograms Product Image

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-if 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 Sinergey? 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, because before the ...more

14 The Flintstones The Flintstones Product Image

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 number 1 on the list!

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

I can't believe the would cast that fat hog Rose O Donnel as Betty Rubble.

15 Underdog Underdog Product Image
16 The Adventures of Rocky and Bullwinkle The Adventures of Rocky and Bullwinkle Product Image

This is one of the more " not bad but not good either" movies I watch. I can tell that most of the production try, expect for the actors, they're bad. But it has the charm of the original plus not the worst movie base on a live action cartoon "cough" dragon Ball and last Airbender " cough".

I didn't even know that there was a live action movie based on this!

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

17 Alvin & The Chipmunks: The Squeakquel Alvin & The Chipmunks: The Squeakquel Product Image

The Worst alvin and the chipmunk movie.

18 Transformers: Revenge of the Fallen Transformers: Revenge of the Fallen Product Image

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

They should be embarrassed making a classic like this.

Love it love it want more of it but its unwatchable.

19 A Fairly Odd Movie: Grow Up, Timmy Turner A Fairly Odd Movie: Grow Up, Timmy Turner Product Image

This movie is just stupid and forgettable!

20 The Smurfs 2 The Smurfs 2 Product Image
21 Bratz: The Movie Bratz: The Movie Product Image

This whole movie is like if Mean Girls was made by somebody 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!

Worst movie ever! Should be #1 on the list!

22 Yogi Bear Yogi Bear Product Image

As much as I hate this movie, It managed to follow the source's formula well, and it felt like the creators had seen the source material (Yogi Bear) before. Even if I hate it, I thought they were trying.

Dan Akryod and Justin Tiberlake are merely doing a Yogi Bear and Boo Boo impersonation.

My childhood is in Hell right now.

23 Inspector Gadget 2 Inspector Gadget 2 Product Image

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

24 The Flintstones in Viva Rock Vegas The Flintstones in Viva Rock Vegas Product Image

Even though this movie seriously reaches the mark of what considers to be the worst movie that is 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, and 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 on it, I would actually care.

Forget about this sequel, I have enough so I will not watch it again.

25 Fat Albert Fat Albert Product Image

I thought he always sucked.

Right next to Shark Tale.
