There are poor and unrealistic excuses for all the shown torture. All seems very artificial constructed for the sake of showing torture and pain. The worst is the story telling, which is chaotic nonsense. Add some classical music elements and there will be people who are delighted about this "piece of art". Even though the torture effects are obviously handmade, which highers the realism a little bit, there are no insects shown in that blood coated scenario. No flys, no ants, no cockroaches, not anything - just bloody pain with an artificial forced kind of poor story and characters who are very unlikeable. Like all the unrealistic things which are shown, the motives of the characters are exaggerated to the maximum to force the impression that those characters would have a good excuse for their behavior, but they are just very sick. The one and a half hour felt one hour longer than it played. I recommend this movie for people who have too much time and like gore, no matter what.
