Query: Very Good Documentary plus Unusual Physical Evidence

This documentary offers unusual locations, encounters and physical evidence (bones and tissue). Eye-witness accounts from mostly new witnesses and law enforcement (minimal reenactments). It features active BF areas in TX, OH, NY, AZ and MN rather than the usual Pacific NW. Three examples of bones and soft tissue are featured (I didn't expect this).I thought the approach was very honest and the production value was comparable to BF docs seen on Travel Channel but not quite as high as History Channel or Discovery. The producer explains that he had worked with Ivan Marx and some of Marx's controversial photos are briefly featured in the film. I'm judging this piece not on it's evidence (you can decide) but rather it's ability to present evidence, present it clearly and offer enough new material to enhance the BF quest. I think it succeeds in this.
