One of Pixar's best. Watched it last night with my wife and son. He loved it the whole way through, although at 4 years old, he didn't quite get the "family hates music because of a great great grandfather abandoning the family" thing at the beginning.
Very touching story. Beautiful animation. Even at 2D it felt like an amazing immersive world. Thought it was interesting how Mexican heaven looks like a combination of Kowloon Walled City and Disney world.
