It's one of the funniest movies of the year easily. It has more visual gags than you can imagine, moves at a quick pace, has surprisingly great effects, and the 3D is vivid and terrific. The action scenes kick ass, the jokes almost all hit on the mark, and you have MISTER T AS A POLICE OFFICER.
I can't emphasize enough that this movie is worth your money-- even a 3D ticket money. I'm praying this one gets an Academy Award nod for Best Animated Film. It's definitely worth it. Not quite as good as Up... but better than the rest of the pack.
