User Reviews: This documentary will be a disappointment for those still hypnotized by conspiracy theories. But it’s one of the best and most informative documentaries on the JFK assassination ever done. It does not refute every conspiracy theory–Vince Bugliosi’s magnificent book already did that. What it does do is get inside the investigation , Lee Oswald, and Jack Ruby better than any documentary so far. There are poignant moments with Ruth Paine, the devout Quaker who took in Marina Oswald and her troubled marriage–only to find that the husband had murdered the president of the United States. Highly recommended.
