You know, I was thinking that this was going to be the worst horror movie I was ever going to see, and I was wrong. (By the way, you can look up the synopsis of the film all over the Internet [if you didn't already know what this film was about], so I'll spare you the details.)
As a celebrated and retired-surgeon of separating siamese twins, Dr. Heiter is obsessed with the idea of a single digestive system. Two stranded tourists and one, make that two, kidnapped motorists later, and you have the human centipede.
As a horror film (content aside), it hits every element: suspense, terror, disgust, fear, excitement for the underdog, empathy, and sadness. You actually care for these characters. You don't get to know that much about each except that the girls are shallow type American tourist party-girls and the lead is a bullheaded Japanese male. Their fate is pretty much carved out from the beginning based on Dr. Heiter's first trial with the centipede. (That's the one I got most upset about.)
The very idea of this movie is beyond disgusting and the real horror lies in the fact that the writer and director sought out medical advice to make sure this movie was 100% medically-accurate. Gee-ross!
As a viewer, you completely put yourself in the place of these unfortunate "siblings" and have no choice but to watch (in utter horror) what happens to them. THAT is real horror; not torture porn, what someone could really conceive of and accomplish.
Tom and Ilona Six did more than their due diligence. The medicine was right, the writing was as good as it can be with one language barrier and two mutes, and they brought the scary. Because, c'mon, are you going to knock on some random German's door when YOUR car breaks down on vacation from now on? Hmmmm?????????
Tom Six hints at an Internet-confirmed sequel...I can't believe that I want to see it. Good job, Tom Six!
Watch the extras, they're totally worth it. Tom Cruise, J-Lo, and Paris Hilton walk into a German doctor's house......
