It was a show designed to appeal to the broadest base possible in order to attract advertisers who bought commercial spots to sell cat litter and toilet paper.
For people who were not overly interested in the subject, it was fascinating...as shown by its popularity and longevity. Not a lot there for those of us who are consumed with the subject or those who hate the standard reality tv formula. But, we are not their target audience. A lot of custom motorcycle mechanics probably didn't watch that Orange County Choppers show either.
It did present the Bigfoot phenomenon to a much larger audience, which was a mixed blessing. It's died down some now, but having every other person in the woods banging sticks together and howling definitely muddied up the waters.
However, I think that these shoes serve an important purpose that is not really mentioned a lot... The expose the next generation to the subject and encourage them to get out and LOOK. How many people out there owe their interest in the field to In Search Of or later Monster Quest?
Maybe the kid who will someday grow up to finally prove that these things exist is sitting there watching reruns of Expedition Bigfoot right now... eagerly awaiting the day that he is old enough to go out there and look for himself.
On a personal note, I originally found pretty much all of the cast members unlikeable. However, I chalk that up to the 2 dimensional nature of reality television characters. A member of the forum recently turned me on to Cliff's podcast, which I am enjoying a great deal. I find myself agreeing with him more often than I expected and find him to be a very likeable fellow.
