The point of the article is not that Cameron borrows ideas from others per se. Everyone does and there is nothing wrong with that, and there is no question that Cameron is a film genius. The problem is that his belief system is caught up in an international environmental fascism which many viewers are consuming in his movies without thinking about what this is really all about. His movies are propaganda tools - not merely entertainment. His genius is that he has managed to do both at the same time - much like Riefensthal herself.
Maybe true, but due to my inexcusable gaff upthread, I really need to just hide for a while...
