Actually it is not a bloodfest. A serial "killer" places people into "games" - he tests them on how far they will go to stay alive. So in fact, he is not the one who kills them, they kill them selves. Behind every "game" there is some sort of point, but mainly he wants to show people that their life is worth living. One of the episodes is with a drug addict who survives (by killing another person) and even though she will be fucked in the head for the rest of her life by the traumatizing experiance of almost dying, she got off the drugs! ya, ya, I know...but you should still see it...it is deffinately not a bloodbath type of movie you're thinking of.
