Well if you make a documentary and nothing happens than it isn't going to sell .. most documentaries are so slanted towards someones personal bias it's insane ..consider most of the action is staged or planned ..rarely is anyone ever in such a good position to take really decent shots of the type of things needed to keep an average viewer interested ..I take all these type / hype films with a big grain of salt .. on the other hand it will bolster someone elses opinion of something they already want to believe
