I have to say this was a pretty good documentary. No one view was given more credence than any other, and the facts were presented in a nice, compact way that anyone not familiar with the assassination can digest and appreciate.
Of the theories, I am most familiar with the official version (which I happen to accept) and the Mafia version. I can say the Mafia version was presented fairly well, and had the necessary footage of James Files. I know Files, I have exchanged several letters with him. He is an interesting guy, very intelligent, but probably not the killer of JFK. His reliance on Charles Nicoletti and John Roselli make his story questionable, because the FBI was closely watching those two Chicago mobsters and would have known their plans if they had any.
Although I generally think the dissenting views are silly, they were presented fairly here, and they do raise a good point. Many, many documents are sealed until 2017. I would love to see those documents. While I am not clear they would actually add any new facts to the JFK murder, they would be an important piece of history just the same.
