Pixar is THE BEST and John Lasseter is a demi-god. Simply.
The story shines, the characters shine, the landscape/setting is amazing, and of course the animation is fine. I had read that the cars were, well, cars, and not so engaging. Whoever wrote that is without a soul (and probably believes in the superiority of animate objects). So see it. It will take many viewings to catch all the humor.
I will note that the only disappointment I had in it was the slight paucity of extra features which is usually a Pixar strength. I find the process of Pixar amazing (and seemingly a healthy model for the rest of us) and always want to see more of it.
