One of the best movies I've seen in years. Smart, intriguing, thrilling, and actually original. The acting was great, and the effects were amazing. I can't speak for standard theaters, but the sound in the IMAX also added a lot. I'd recommend this to everyone who actually likes to think when watching a movie.
This was a great movie. It has the artistry of Wall-E, the heart of Finding Nemo, the adventure of the Incredibles, and the laughs of all of them put together. As with all Pixar films, it has great characters and a solid, quality story. And it's possiblyt he funniest movie I've ever seen.
I only wish I had known less about the story than I did before I saw it, because it woudl have made it that much better. The only other negative was that the theater desperately needs to clean their screen. The digital projection made that very obvious.
