Just found Human Centipede on Syfy channel, 45 mins in.
May watch a little bit to see what all the fuss is about. Probably wont watch it all as so far it doesnt look great. Kind of B movie-ish.
When I saw it on Syfy I immediately thought of this thread.
I gave it a try but wasn't too impressed. A fairly standard story but based on a gross idea that just feels wrong to have a film about it.
It wasn't too visually gratuitous like I thought it might be, I was instead rather indifferent to it all. It was just my imagination that left a bad taste in my mouth, but after about half an hour I was happily eating again.
