The acting was not very good and parts of the interactions between the victims was a bit forced and unrealistic...but, I did keep my attention throughout. As far as realism, the actors didn't convey as much pain as they actually would have felt. If you have a fingernail ripped out like that, you are going to be writhing on the floor for a long time and the throbbing from your finger would render that hand useless and would render you unable to be able to focus on anything until the gruesome pain subsided. Which would take a long time. Most of them had multiple fingernails ripped out. Also, when the one guy has the pot of boiling water poured over his lower half...he would have been unable to do anything more...yet we see him in the next scene without any discernible evidence of pain. In fact, we see him walking around like nothing has happened to him. The realism needs a lot of work.
