content: Disappointing. MST3000 works on two levels--the movie itself, and the riffs from the audience of three. "Cave Dwellers" is pretty poor. Often, that gives Mike and the Bots fodder for their best humor; however, they had a down day doing this one. It takes a little inspiration to transcend the lack of entertainment value in a bad film. I consider myself a moderately hard core MST3000 fan, but this one just didn't make it over the hump.
