Full of fun and joy, for every girl and boy! (And the parents!)
The story is great: Full of emotion, charm, suspenseful twists and wit. The characters, and their motivations, are well thought-out. The series could not have ended any better.
I saw it in 3D, but you don't really need to. I am sure the movie works almost equally as well in 2D.
The opening Pixar short, Day & Night, was massively creative, to say the least.
