Total non-sense. I have been to tibit. And all of the stuff they shown in the movie is either total bullsh.t or extremely dramatized. In essence, it is just a political film used to undermine the image of China.
Pitched for a sympathetic American audience, the documentary goes for shock with the filmmakers' first trip to "the altar of the world" in 1987, when they happened to be caught in an uprising of monks that was violently crushed by the Chinese army.
