Great animation, but bounds from perfect.
Reading reviews from other people, I don't see what the big deal about this animation is.
Pros: It is, undoubtedly great. It's extremely funny, the voice acting was spot on, and an amazing story line.
Cons: The animation was pretty stale for the quality of it. With the story and the comedy the animation could have been a lot better. And a lot of the technical features of a film seemed wrong here. The transitions between scenes were horrible, and at times, it moved way to fast.
But, the good triumphs over the bad. In the end the movie is still hilarious, and I can't wait for a sequel.
