I watched the trailer and the part where he challenges the claims in JFK. The former offered little insight into what the film was like, though hilariously he found a CT at DP on the 50th anniversary who was pushing the thoroughly discredited notion Kennedy was going to abolish the Fed.
The latter was weak, evidence in support of his claims was scant, he once even oddly cited another movie. And for his repeated insistence that CTs lie his account was often distorted or misleading. For example he said (accurately IMO) that it was an open question ifr JFK would have pulled out of Vietnam after the election but it's pretty clear he never would have escalated US involvement, at least not to the levels LBJ did. And his account of why LBJ dropped out of the race in '68 was quite dishonest (speaking of lying!)
