I agree that a lot of his things, like a lot if not most of all paranormal "proof", is very far fetched and stretched to the max, like random faces seen in foliage mistaken for bigfeet peeking from behind trees. But there's a few particular videos that are very promising, if not the best proof we have of bigfoot today. Like his vocalization videos and many of his back camera stuff. Also the creepiest video of a cryptid I have seen is his dogman video. You can see it quite clearly, then it goes away. Fake or not, something was there looking at him, then it got away back into the bushes, and it's very eerie looking.
Regardless, I think that this guy is genuine simple because of the sheer mass of material he has. Almost every single proof of bigfoot or anything else paranormal is a very poor quality shaky shot of a coupe of seconds, yet he managed to get all these quality shots. Even so, it's not a very high quality but if this theory that the bigfeet can somehow cloak themselves, many things about them could have been explained.
I'm particularly fond of the idea that bigfeet are spiritual beings and not exactly giant ape-men that live in the woods.
