I had heard of it before as well and had to see if it was as disturbing as I had heard. It was pretty hard to sit through.It's pretty hard to offend me, but 120 Days Of Sodom did the trick.
I knew of the movie before I saw the Cinema Snob review/riff of it, but had never saw it. It's one of those movies that I'm sort of interesting in seeing it cause of the reactions people have to it. But at the same time, I don't think I could make it through it.
Thanks for the heads up.
