This movie, especially with the graphics and effects of the IMAX 3D, is a completely immersive experience. You feel as if you are alongside with the camera. I don't heartily support the rather obvious comparison to the American treatment of the Native American Indians during our country's founding, however, that will not keep if from being my near favorite of all time movie - right alongside the Lord of the Rings trilogy.
Go see it! I will be seeing it at least once more in the IMAX before I get my own copy for home. (been wondering what could justify getting a 3D capable home theater - this could be it!)
