The white guy notices that the peace-loving natives are much cooler than the greedy corporate tools and the bloodthirsty U.S. military types he came over with. He goes to live with the natives, and, in short order, he’s the most awesome member of their tribe. He has sex with their hottest babe. He learns to jump through the jungle and ride horses. It turns out that he’s even got more guts and athletic prowess than they do. He flies the big red bird that no one in generations has been able to master.

Along the way, he has his consciousness raised. The peace-loving natives are at one with nature, and even have a fiber-optic cable sticking out of their bodies that they can plug into horses and trees, which is like Horse Whispering without the wireless technology. Because they are not corrupted by things like literacy, cellphones and blockbuster movies, they have deep and tranquil souls.

The natives help the white guy discover that he, too, has a deep and tranquil soul.

The natives have hot bodies and perfect ecological sensibilities, but they are natural creatures, not history-making ones. When the military-industrial complex comes in to strip mine their homes, they need a White Messiah to lead and inspire the defense.

Our hero leaps in, with the help of a pack of dinosaurs summoned by Mother Earth. As he and his fellow freedom fighters kill wave after wave of Marines or former Marines or whatever they are, he achieves the ultimate prize: He is accepted by the natives and can spend the rest of his life in their excellent culture.

Cameron’s handling of the White Messiah fable is not the reason “Avatar” is such a huge global hit. As John Podhoretz wrote in The Weekly Standard, “Cameron has simply used these familiar bromides as shorthand to give his special-effects spectacular some resonance.” The plotline gives global audiences a chance to see American troops get killed. It offers useful hooks on which McDonald’s and other corporations can hang their tie-in campaigns.

Still, would it be totally annoying to point out that the whole White Messiah fable, especially as Cameron applies it, is kind of offensive?
