I know, I know, I cant just keep copying Roger Ebert's reviews here. I dont usually read his stuff but was only following him for Cannes and came across this gem.
The Human Centipede - 'It's not death itself that's so bad. It's what you might have to go through to get there. No horror film I've seen inflicts more terrible things on its victims than “The Human Centipede.” You would have to be very brave to choose this ordeal over simply being murdered. Maybe you'd need to also be insane.
I'm about to describe what happens to the film's victims. This will be a spoiler. I don't care, because (1) the details are common knowledge in horror film circles, and (2) if you don't know, you may be grateful to be warned. This is a movie I don't think I should be coy about....
Heiter plans to join his victims by sewing together their mouths and anuses, all in a row, so the food goes in at the front and comes out at the rear. They will move on their hands and knees like an insect. You don't want to be part of the Human Centipede at all, but you most certainly don't want to be in the middle...
I have long attempted to take a generic approach. In other words, is a film true to its genre and does it deliver what its audiences presumably expect? “The Human Centipede” scores high on this scale. It is depraved and disgusting enough to satisfy the most demanding midnight movie fan. And it's not simply an exploitation film...
I am required to award stars to movies I review. This time, I refuse to do it. The star rating system is unsuited to this film. Is the movie good? Is it bad? Does it matter? It is what it is and occupies a world where the stars don't shine.'
The entire review is worth reading.
