Top 10 Animated Movies Based on a TV series

1. How I Spent My Vacation - a Tiny Toon Adventures film that is so good that it should have been released into theaters over direct-to-video. The movie shows how each of the main characters from the show doing during their summer break. Mostly focusing Plucky's road trip to hell and Buster and Babs journey downriver. Making this movie best remembered for it's slapstick and humor.
   
2. Batman: Mask of the Phantasm - based on the hit animated series, this Batman movie was released in theaters in 1993. Sadly, it did little in the box-office mainly because Warner Brothers focused more on advertising for that awful Batman Forever movie. It became more popular when it was being sold on home video. So popular that Warner Brothers made more films like Subzero and Return of the Joker that are equally as good as the first.
   
3. South Park: Bigger, Longer and Uncut - unlike a the ones below, this one was given strong effort into giving an original story for an adult cartoon show and providing it with memorable musical numbers.
   
4. The Chipmunk Adventure - putting our favorite Chipmunks and Chippetes in a race around-the-world story...Genius!!! The animation is really topnotch especially since a couple of animators from Disney worked on it. And who could forget that song: The Girls and Boys of Rock and Roll.
   
5. The Simpsons Movie - Despite it mostly being just an 87 minute episode, it was still hilariously memorable. Not to mention the introduction to the newest addition to the Simpson family cast, Spider-Pig.
   
6. Duck Tales the Movie: Treasure of the Lost Lamp - an underrated Disney film that deserves a DVD or Blueray release.
7. Scooby-Doo on Zombie Island - One of the rare Scooby-Doo movies that's actually scary for a family kids film. But it's much better compared to that live-action version.
   
8. The Spongebob SquarePants Movie - The only real good movie made by Nickelodeon that everyone could love. My only downside with it is that I was expecting it to be the conclusion of the entire show. But if that happened, Nickelodeon would be out of business.
   
9. The Rugrats Movie - The first Nicktoons movie based on their most popular cartoon, Rugrats. The film seems to force itself into scary and intense situations just to compete with Disney. Overall, it's more enjoyable to watch for little kids or people who grew up watching the show.
10. The Powerpuff Girls Movie - A prequel that explains the origin of the PPGs even though we've already heard it countless times in the opening credits. The only clever part of the film I liked was Mojo Jojo's plan to "make the town a better place."
