off hand, I remember that flow chart being ridiculously inaccurate. then you have the famed interviews with necrobutcher (where he's completely wasted and thus isn't a true representation of himself or the bm scene) and gaahl (which was just gaahl playing the part). then there's interviews with alice cooper, who has absolutely nothing to do with any part of the metal scene. those are the only things I'm remembering right now, as I haven't seen the docu since it came out (and really don't care to.)
