You want some dumb fun? Here's a movie for you. This sci-fi flick has two significant things going for it: First, it doesn't take itself seriously. Second, it has Chris Pratt as its star - and he doesn't take himself seriously either. What's the story? Um, something about space. And aliens. And a group of underdogs joining together to beat the big guys. Its cheeky attitude and its throwback sensibility (including a killer oldies soundtrack) made this the sleeper hit of the summer.
