I've been watching this show since season one. I think the team has found some interesting evidence on camera. One thing that I always wonder at with research teams; why not stay for a long time in one area? (although Ron Morehead and his fellow researchers to go back to the same area in Northern California, and have gained a lot of experiences there.) The team thinks of Bigfoot as just an animal, though Ron Le Blanc does seem to accept paranormal explanations.
Season 4, episode 1 brought the team to Prince Wales island in Alaska. It's said the Bigfoot creatures there are more aggressive, more violent.
Stumbling around in the dark in unfamiliar places seems dangerous, which is something the team does a lot, especially Russel Acord, who goes off on his own. (along with at least one camera man of course.) And why didn't he pick up the skin and fur sample right away instead of chasing a creature that surely was aware of him and, if it were Bigfoot, was aware of him long before Acord was cognizant of Bigfoot. Sure enough, when he returned to the spot, the fur was gone.
Overall though Expedition Bigfoot is a good program.
