First off, let me begin by saying the only reason I gave this movie ONE star is because I was unable to give it NO stars.
The idea behind the movie, as mentioned in several of the reviews here, is quite terrifying and would made for a thrilling novel. The IDEA that someone would pay for the sick pleasure of torturing a random (or sometimes randomly picked from a series of preferences listed by the torture-er to be) person is truly horrific and a serious offense to the humane, not to mention dealing a massive blow to the psyche. You are chosen, drugged, chained to a chair, and are forced to endure hideous and abominable tortures, agonizing pain, and a prolonged, longed-for death. I'd be longing for death too after an ordeal like that. It's a psychiatrist's worst nightmare.
Because of the premise and the idea, I had actually WANTED to see this movie and I fought for days to rent it.
Unfortunately, WHEN I saw this movie I was completely disappointed and more than a little disgusted. The entire first half of the movie is basically a poorly-done porn flick pretending to be horror, while the second half is nothing but an unintelligent splatterfest of gore. It makes a body sick, rather than terrifying the mind. In fact, at one point, I was truly forced to leave the living room and vomit. Thank god I didn't see this on the big screen. I'd have spewed my dinner on all unsuspecting moviegoers on my marathon run to the restroom. And I'm a horror buff. I love horror. This movie, this isn't horror. It's just sick on all counts of human decency.
The characters themselves are shallow, two-dimensional, unbelievable, and nothing but a bunch of horny sex-mongers who apparently don't care if they get an STD from any of the MANY prostitutes they bang in the process of their "Eurotrip". I found myself hoping they'd die from a disease or a virus before the gross bit of the movie was even HINTED at. Had it not been for the title at the beginning of the film (if it can be called such) I found myself wondering if I had gone into the wrong theater.
The only Likable character is the poor Japanese girl who gets her eye pulled out and dies by jumping in front of a train. I actually felt SORRY for her, but not for anyone else in this disgusting excuse for a "movie"...
