The Human Centipede: First Sequence is a newly-released schlock-horror film about a crazy surgeon who attempts to make a human centipede by sewing people together mouth-to-butt. Roger Ebert refused to apply the star system to it in his review. From the Sun Times:
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...Roger Ebert reviews The Human Centipede (Thanks, Lisa Mumbach!)
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.
And here's The Awl's review, "Horror Chick: Do Not See 'The Human Centipede' Unless You Are a Sick, Sick Puppy, And Even Then Reconsider"
UPDATE: And the requisite Tumblr blog for this depraved flick, "Behind the Behind," from UPSO and pals.
