As for the plot...crippled ex-Marine starts as a mercenary working for a mining corporation. Joins natives in Avatar form to understand them and study their weaknesses.
Starts to appreciate their society and sees that the corporation he’s working for is destroying the native people and land. Mayhem ensues. What’s the problem????
The writer/director says it's about "creeping imperialism disguised as patriotism," "the way you interact with nature," the way we are "trashing our world and maybe condemning ourselves to a grim future," American conduct of the War on Terror "that cost several hundreds of thousands of Iraqi lives," shock and awe and "I think there's a moral responsibility to understand that." He even said that it isn't "necessarily a bad thing" that the ash raining down on the Na'Vi after the evil white folks attack resembles the ash coming down on Ground Zero.
