This is a surprisingly fun movie, and I don't even mean that in a "Haw haw haw! Lookit the crappy special effects! Hee-yuk!" way.
I'm convinced it's a comedy, or at least the parts with Bill Moseley are. The whole setup that Leatherface and his family have is way too complicated to be taken seriously even for a minute. And the movie even had Joe Bob Briggs in it, at least until his scene got cut out.
Don't get me wrong. It's not a "good" movie, and you have to be in the right kind of mood for it. But I had a lot of fun watching it. Most enjoyable.
