Since it opened last week, James Cameron's much-anticipated film "Avatar" has won praise from movie critics and been a juggernaut at the box office. But some who have seen the film say that it contains hidden messages that are anti-war, pro-environment, and perhaps even racist.
For the benefit of those who haven't seen the film, a little nonspoiler background might be useful. The story is set in the year 2154 when Earth's inhabitants, having used up most of their natural resources through decades of living in excess, plan to use military force to conquer Pandora, a moon roughly the same size as Earth. Pandora, inhabited by a wise, peaceful, and nature-respecting people with blue skin called the Na'vi, is rich in a resource that the people of Earth desperately need.
