In Hollywood, it’s not hard to find a borderline snuff film that turns the stomach and loosens the sphincter. Some of the most disturbing movies ever made fall into that category. But there is another type of disturbing movie that may not shed even a drop of blood, yet shakes the audience to their cores by revealing uncomfortable truths, secret perversions, or a gleeful, careless violence in humanity as a whole. This latter category of movie may not even consist of “good”, “classic” or “cult” movies, but they nonetheless will leave you squirming awake at night.
