I'm not calling this a review because I'm not going to give you specific, listed points as to why YOU SHOULD GO SEE THIS MOVIE.
I can't tell you what a good time it was. Really. I knew nothing about it beforehand (which is usually the best way to be pleasantly surprised by a good movie, I find) and it was fantastic and really funny at times. It's so easy to mess up a movie that's intended for kids these days, in my opinion, and this one was just great.
GO SEE!
