@Wetrix Yeah and i get the impression that some of the people in the film wanted to make a bigger deal out of themselves than they were.

I actually learned a lot from this interview here https://invidio.us/watch?v=yjn6wK01cqk whether people like or trust this guy, he is very good at what he does, very candid about it and what he believes and really goes into depth about his field of work. I don't necessarily agree with him on what he does but i gleaned some info on how it all works and that is always good.
