I give it a 65%. (Spoilers follow)
It delivered exactly what it promised. Three people are conjoined anus to mouth to create a siamese triplet connected through their gastronomical tract.
Well its almost what it promises; three people mean 12 limbs which isn't exactly a centipede but you get the point.
It fits in its genre and I like the direction and 90% of the acting. I love the way it is shot and enjoy the subtitles.
Two dumb American girls are touring Europe there car gets a flat and they go looking for help. But rather than walk down the road they go into the woods to find help. There is my first problem. I don't feel sorry for them because they are idiots. The main lady in Hostel 2 is a badass and so I cheer for her.
They knock on a door and a man who is clearly a bad dude, there isn't even an attempt at suspense to make it feel like they are safe, answers and asks questions that are super suspicious. The girls go in and are drugged. They wake up in a hospital setting and are told the plan to conjoin them.
The first girl escapes (notice How I am not using their names because I don't know them) and acts like an idiot when trying to escape, and then there is a really good scene in a pool. I won't ruin it for you. But needless to say she doesn't escape because she sucks. Then we get the operation.
It is gruesome and gut wrenching although I am sure to very medically accurate.
The next 30-40 minutes is about life as a human centipede.
Then it gets a little cool and there is a police investigation, the centipede fights back and attempts escape up some stairs (which is handled really well, both directorially and by the creature itself), and then there is a final show down and its gruesome and terrible.
I didn't really like it.
The way the movie is shot reminds me of TEETH which is a much better "what if.. movie" but technically the film is very clean and has a very specific style which I really like. It was simply laking in depth. The camera work feigned it a little bit but not enough.
For example I never got to find out why creating this centipede was necessary. What is up with this doctor and what is his motivation? Obviously I care about these characters to the point that I don't want them to be in this situation but I don't have any personal connection to them. Very little development.
The two girls that we have been with from the beginning are the middle and the end so we don't get to hear what either of them have to say because their mouths are sewn shut, and the front piece is this Japanese guy that doesn't speak english and I don't care about.
Its just a weird movie that has no point. I mean really no point. Maybe its me but I just shut down and wasn't even really grossed out by it after a while because I just didn't care, it became nothing except a little obscure movie that now I can talk about having seen.
The Doctor says that he doesn't like human beings and likes dogs. He also treats the centipede like a dog. this movie would have been better if that was the way it went, he tried to turn a man into a dog. I think that would be more grotesque and more realistic thusly more scary.
