for horror fans, this movie is worth seeing, although you have to have a strong stomach. the first 40 minutes of the movie are filled with constant drugs, nudity, sex, and drinking. the movie gets pretty trippy after a while, because things start to seem very weird once their friend is missing. not to long later there is around 45 minutes of constant horrific torture. (a man pleads to let him leave so the bad guy slices the back of both of his feet and tells him to leave, the man tries to walk but it just splits his fees right open.) at other times a man has a ball tied to his mouth so he cant be heard but he is so horrified that he vomits, the puke has no ware to go so he chokes on it. you also see a women get a blow torch to the face, resulting in her eye hanging out and being cut from her socket. i think this movie is under rated because there is always so much hype about the saw movies and how theres nothing worse. i am telling you this movie makes saw look like wall-E. aside from all this bad stuff, it is interesting to think about how people could be so sinister to want to do such horrid things. i like this movie and you feel up for it then go for it, but keep in mind you probably have not seen anything as bad as this before in film
