One thing I like about Pixar films is how the happy ending isn't always what you think it'll be. The toys don't go with Andy to college, Gusteau's restaurant gets closed down, Mike and Sulley get kicked out of university, Carl never gets Ellie to Paradise Falls. But they find out that what they wanted isn't necessarily what they needed, and I really like the fact that kids get to learn that life doesn't always turn out the way they dreamed and that's okay.
