10. Henry Portrait of a Serial Killer - Snuff Home Invasion (1986)
Not exactly the world's cheeriest film, Henry Portrait of a Serial Killer has been doing the rounds, depressing the tits off viewers since 1986. This grim, uncompromising, totally unglamorous look at Serial Killing has a number of depressing scenes as Henry and his hideous lackey Otis go around committing acts of random murder. The most contentious scene is whenever Henry and Otis stage a home invasion, slaughter the entire family, record it on a hand-camera and then watch it at home for their own amusement. This is bordering on snuff territory. Otis, who could at best be described as a polymorphous pervert, fondles the dead woman's boobs. This is bordering on necrophiliac territory. Do you see why the scene was so controversial?
