The Imax 3-D experience was incredible! It is long, but your attention will not waiver from the screen. The story line is nothing new, the indigenious people are modeled after native americans, their plight is the same.....same sad story.... told in sci-fi. And surprise (not)... the hero is a white guy wannabe native..... however, the women in the film are strong and the spiritual connection to the all things is magical. An outstanding experience. I would see it again.
