Just saw it for the second time. It's so rare that a sequel is ever as good as the original, but Pixar has done an unbelievable job with the Toy Story movies. Everything progressed logically up to this point, and it doesn't feel like anything was tacked on at the end just to make an extra buck. They tied up all the loose ends and made probably the most satisfying conclusion to a series that I've ever seen.
On a side note, there were SO many people around my age (21-26) in the theater. Pixar must have known that all the kids who remember seeing the original Toy Story when it came out would be lining up to see how the whole story ends.
