Native north-American Indians will LOVE this movie; also tree hugger.
It's very PC (Politically Correct) !!!
It's got one serious scientific/economic/health problem.
It forgets some aspects of evolution, it ignores the effect of disease when hi-tech does not exist;
such as: it ignores the effect of:
cancer, bacteria, viruses, and fungus (etc., etc., ....) on halving life-expectancy !
If you like to live in a bug infested tropical forest,
and die at 40 instead of 80, then you will love this movie. .
