This horrifying flick seems to do its best in blurring and romanticizing events so much that way things actually happened becomes romanticed and messed. Which is of course the main reason of the movie. Characters doesn't show most anything from real people, the events are of course 'based on actual guideline', but there's just that something(a lot) which doesn't fit in (too much uncorrectness to mention).
Somehow, the Indian characters seem more white that they should (as most are played by Indian) and somehow white characters seem more like bureacrates than actual officers and congressmen. And of course in most conversations them (w.a.s.p.) get the last word. And of course them victims (massacred) weren't saints themselves, and of course them religious movement was actually hoax, and of course all of it happened in more romantic times in distant past. And besides of all these things, the film is actually quite boring.
Some credit goes to guidelines in the end of the movie, which at least seem to be correct.
