Agreed, who knows what the on-screen personalities knew or when they knew it. We have no idea in what sequence the various scenes were actually shot. It would be interesting to know how the concept of the show was presented to Dr. Mayor. She presents as a serious researcher with a solid reputation in her field; it's difficult to believe she would have signed on knowing in advance that the production would amount to little more than an over hyped hoax. I really hope that her reputation isn't damaged in the eyes of her peers (in the unlikely event any of them actually watched the show).
I don't view this from the perspective of egos or the "Bigfoot community". Trust is another matter entirely, to my eyes the production is no more or less than an elaborate hoax, a web of lies and deception from beginning to end presented to viewers as a serious attempt to explore the subject. The premise of the show, that the timing and locale were chosen based on applying an advanced algorithm to some huge number of sighting reports, a lie. The locale is a remote wilderness area; this is a lie on it's face as motorized transport is illegal in designated wilderness and twice a lie as the actual locale is a privately owned commercial operation. The graphic used throughout the production, presented as a bird's eye view of the research area, was a fabrication massively misrepresenting both the physical features and scale of the research area. I could continue with the mysterious old wrecked pickup stumbled upon, the cemetary in the middle of the forest, the "deadly cinnabar" mine, all misrepresentations and/or outright lies. So, was there any truth at all in this production? About the only thing I think was at least possibly true was the deer seen in the thermal across the meadow. How much of the rest was hoaxed by the crew, possibly without the knowledge of the cast? I don't like being lied to, regardless of the subject, and I don't trust liars. Plug another subject in place of Bigfoot in the title; Expedition Tasmanian Tiger, Expedition Amelia Earhardt, Expedition (your choice here), a hoax is a hoax, a lie is a lie and lost trust is very difficult to overcome.
