Ok, I'm going to open up a bit of controversy and say, yes it was super disgusting and horrifically twisted and gross. **But** that essentially makes it good. I mean if a movie has you thinking about it afterwards, even if the reason you're thinking about it is because how horrific or disgusting it was then the movie has gotten a reaction from you and that's the point.My wife and I were recently wondering the very same thing about The Human Centipede.
(Clarification: We haven't seen it and we don't intend to see it. The trailer was more than enough. The only thing more disturbing than the fact that this movie even exists is that, apparently, a sequel is already in the works.)
