I disagree completely. The PG film is a motion picture with scores of frames showing front, back, and right side of the subject.......in motion. It was analyzed by well recognized experts for 50 years now. There were footprint casts poured at the scene, and they match others poured in the region previously. Two men witnessed the creature with their eyes at the filming. Other parties visited and analyzed the scene over the subsequent 10 days, also seeing and photographing the footprints. People visit and analyze the site to this day, half a century later.
There is no valid comparison whatsoever.
