10 Underrated Animated Movies That Deserve A Second Chance

10. Planet 51

One of Dwayne Johnson's earlier movies, prior to being the biggest star in Hollywood, sees him star as an astronaut who lands on a planet full of green aliens. However, on the 1950's-inspired planet, the Earth astronaut is the alien and he needs to get home! Sound familiar?

That's the simple premise of Planet 51, the first movie from studio Ilion Animation. Planet 51 came out in late 2009 to little fanfare - scoring a pitiful 21% on Rotten Tomatoes. This is one instance though where critics were being a tad uptight.

Planet 51 is actually a pretty funny movie, filled with pop-culture references, slick animation, and a stellar voice cast consisting of Dwayne Johnson, Jessica Biel, Justin Long, Gary Oldman, John Cleese, Sean William Scott, and James Corden. Planet 51 isn't going to make you re-think life but it will make you laugh a few times.
