10 Films You Must Never Watch With Your Parents

7. Natural Born Killers

Oliver Stone's account of fictional serial killers Mickey and Mallory Knoxx has been described as one of the most controversial films of all time. Relentless swearing, sexual abuse in numerous forms and so much violence it'd make John Kramer blush, it's certainly an extreme movie with eccentric direction creating a totally disorienting experience. Setting out to satirise how the media mythicises criminals (a point that hasn't lost any bite in the two decades since its release), many critics at the time couldn't get past how intense the imagery was.

At times it feels almost sadistic; revealing Mal's father's abuse through the trappings of a three-camera sitcom and pushing an already awkward sex scene through the roof with the reveal of hostage stuck watching the whole thing are two moments that hard to forget The film inspired a spate of copycat killers, in morbid fashion proving what Stone was trying to say.

The Worst Bit: The implied rape of the duo's hostage isn't an easy watch, but the matricide by fire is so terrifying it takes the prize here.
