Ya I know. It's a "children's" movie; but so was Toy Story, Ratatouille, and Finding Nemo, and those movies are classics.
I recently saw this the other day; a day after watching the severely disappointing "Wanted." It was great. It was wonderful. It was incredible.
I swear those bastards at Pixar made this movie just to challenge themselves. Pixar has always been great with their animation. The way they portray body language is absolutely phenomenal. So I'm guessing, one day during brainstorming they come up with the idea of having a character that can't talk, thus having to solely rely on body language to communicate. Then to top it off, they make the main character a robot.
Genius.
Go out and watch it with your girlfriend or with your little brother/sister. It's a damn good movie, but if you don't trust me, just look it up at rottentomatoes.
