14 Disturbing Horror Movies That You Might Just Regret Watching

• What It's About: A young, innocent girl finds herself possessed by a violent, expletive-slinging demon. As one priest tries to exorcise the demon from her body, all hell breaks loose in the most literal way.
• Why It's Disturbing: You might think a girl's head turning all the way around is as bad as it gets, but you'd be wrong. Perhaps the most chilling sequence involves a masturbation sequence that includes plenty of cursing and a crucifix.

You can watch this one on Netflix.
