I enjoy reading pieces like this where "experts" weigh in on the authenticity of various types of evidence. It reminds me of all the medical doctors, special effects types, historians, film experts, etc. who validated the alien autopsy film of the 90s. I well remember Bell's film historian/expert Bob Shell guaranteeing the authenticity of the autopsy film on C2C in 1995.
The "Astonishing Legends" guys have a multi-part show, better than fifteen hours total, on the Patterson-Gimlin film. There are a number of "dueling experts" throughout the series (anthropologists, primatologists, costume designers, special effects types, film analysts, etc) who give their considered opinions on the film. My favorite was the guy who has made a living in the film industry for many years playing various monsters, apes, cryptos etc., both in and out of costumes. He had some really insightful comments relative to Patty's gait.
This series is far and away the best podcast effort I've ever heard, going above and beyond to give all sides of the argument as to whether the film is genuine.
