This could be as real as it gets, as far as documentaries go. The protagonist is trying to get the truth out and give some piece of mind to families about how their relatives died and why. In my opinion the Protagonist went to far on some cases. He got the answers he wanted but was it really worth it to spend most your life in solitary confinement? The Director is amazing to be able to film all these events and let the protagonist do things his own way and not get involved is unbelievable. the director takes a lot of risks and i believe that is why he made a great film that does not hide the truth, you see things as they are really happening not as he would like you to see them. Although I do not like how the protagonist approached things, he was strong man and new what he wanted and he would do anything to get it. His passion was to get the truth and that is what he did.
