Incredible in IMAX 3D. You lose yourself in the scenery and the story. But I did not expect the amount of action and violence based on the trailers I had seen. Violence may be a little too much for PG13 rating and definitely too much for younger kids. But this is definitely a notch above Lord of the Rings movies which were also incredible. IMAX 3D puts you into the movie like you are an observer actually there. Regular 3D may also be good but for $2 more I would go with IMAX if you can get in!
