Get the uncut (NC-17) version from France!
Under Alternate Versions, it says that the French release is uncut. Well, I ordered it off of Amazon.fr and it's true! I know this isn't the greatest movie, but it's still a fun horror movie, and the scenes that were cut (mostly scenes of violence) were just made much more brutal and graphic. The beginning has even changed, where the person being skinned is actually alive.
Definitely recommended for horror fans and people who need to see everything uncut like me (it's a problem, I know).
