I give this movie 3 stars only for its interesting visuals. The story is an utterly trite regurgitation of Pocahontas and Dances with Wolves: See James Cameron saying European/white civilization is bad. See James Cameron saying technology is bad. See James Cameron saying capitalism is bad. See James Cameron saying primitives are naturally wiser, kinder, more ethical, more moral, more "in touch with nature", etc. etc. ad nauseum. Of course, Cameron himself made a gazillion bucks with a capitalist enterprise, and has more vehicles and more technology created by the civilization he rakes over the coals than 99 percent of the population, and isn't interested in giving it all up while preaching that the rest of us have to make do with less, but people are obviously untroubled by that.

And, of course, none of the people oohing and ahhing over the primitive culture depicted here have any interest in chucking it all going off to live in the rain forest while wearing a loin cloth, including Cameron, but that's also to be overlooked.
