The long appendages freak me out and the word centipede is extremely unpleasing after a certain movie. I like horror not scuffs
I think you mean "Snuffs"? In which that movie is not a Snuff film. Snuff films are not on Netflix and the likes, though there is some that are rather commonly floating around the net.
I believe that Faces of Death is the only actually circulated Snuff films.
If we get techincal, The Crow is a Snuff film, as they used the footage of him being shot for real.
However the Human Centipede is not a Snuff film. The classification of Snuff, means the death is real. The person is really dying, that is real blood, ect. That is what a Snuff film is, and human centipede doesn't classify. Snuff Films, with a few exceptions, are highly illegal.
That does not stop them from being on the internet however. I have had the displeasure of being linked and watching part of a few of the popular ones, before throwing up and questioning what the hell is wrong with humanity. One in particular, a innocent homeless man, is sleeping on the street and is brutally murdered for real, it's vile, and it's on the internet.
To be clear I don't like that movie either, it's vile. The most Vile Horror movie I find watchable and like would be House of a 1000 corpses and Devil's Rejects, and those are pretty bad.
