These movies distrub me based on the fact that all torture and killing devices are based off of real inventions that people used on each other in the Dark Ages. I don't like being reminded of the violence that we can sometimes ignorantly place upon each other. Other than that the premise of the movie is excellent.
Give a man fire, he'll be warm for a night. Light a man on fire, and he'll be warm for the rest of his life.
An apple a day, thrown hard enough, will keep anyone away.
