I think you guys are being too hard on it. You've seen more gore in an R-rated film in a theater? Which one? You can't really compare it to the cult gore stuff because the MPAA draws a line at some point.

That being said, I though it was pretty disgusting and disturbing. The most visually disturbing thing I've seen on the big screen. I'd read this thread before I saw it actually so I was prepared for the story to be slow but it wasn't. I felt like I got my moneys worth.
