The film is truly an homage to the great films of yesteryear. The visual beauty is the culmination of a lot of different work: Cinematography, set design, costume, and visual effects. It is truly moving. The cast is excellent, particularly, the kids.
I saw the film in 2D because my wife and I both hate 3D. I cannot imagine how putting this film in 3D could make it any better. The cinematography implied plenty of depth without the need for headache-inducing gimmickry.
I highly recommend the film to everyone.
