2. Saw
Saw has been criticized as everything under the sun from sadistic torture porn with no purpose whatsoever in cinema to legitimately brilliant and full of provocative moral themes. Regardless of what you or I think though this film blew audiences away and made gangbusters at the box office on an insanely small budget. I personally enjoyed the morality conflict of someone being tested in a tortuous way that also revolves around rising above dangerous or evil flaws. Its twisted but the act of achieving atonement and overcoming flaws through these barbaric methods was an ingenious approach to horror. Somewhere along the way though, the overarching story got too contrived and bloated leaving the series everything its original detractors called it out as; torture porn where you go and watch people die in sadistically elaborate ways. http://youtu.be/HKPy5RWuqNA Well always have the original though, complete with one of the greatest twists to ever grace cinema, an iconic musical theme, and an unforgettably morally twisted villain who was unfortunately ran into the ground.
