Overrated, of course. Great, yes... There was nothing stunning about this movie, but it did it's job. I'd have liked it more if the internet crowd stopped hyping it. But whatever.
I really think that this movie is one of the most awesome creations in history. Great story, cool animation, good moral. To all the reviewers talking about how their kids didn't understand it, maybe the kids are just dumb. It's smart enough for adults and stimulating enough for children. I'm happy that I saw it in Emeryville, home of Pixar. Lots of people involved in the film were sitting in the audience.
