Think of the storyline of "Dances with Wolves"..........Greedy, technologically superior group of life forms try to plunder low-tech, spiritually connected group of life forms' resources. But the ending of this movie is better----it's more hopeful, not so sad.
I usually don't go to movies at the theatre, and I rarely see them more than once ; Netflix 99%of the time. Saw this in IMAX 3-D and was totally amazed. I REALLY want to see this one again, maybe this weekend.
