10 More Incredible Horror Movies You’ll Never Watch Again (And Why)

10. The Girl Next Door

Based on Jack Ketchum's 1989 novel of the same name, Gregory Wilson's soul-crushing The Girl Next Door revolves around recently orphaned sisters Meg and Susan who've been taken in by their Aunt Ruth. 

Still shaken by her parents' death, Meg hopes to be embraced by her new family. Instead, Ruth and her sons subject Meg to the cruellest torture imaginable. For no real reason, Ruth humiliates and beats her niece, and encourages her children to do the same. The wicked aunt has Meg bound and stripped in the basement, leaving her starved and dehydrated for days on end. Any time Meg behaves defiantly, Ruth takes it out on Meg's disabled sister by spanking her.

Just to prove Ruth's deplorability has no bounds, she invites kids from the neighbourhood to pummel Meg, solely for her own amusement. To ensure Meg doesn't succumb to her injuries, Ruth stops her from bleeding out... by cauterising her wounds with cigarettes.

Though Ruth gets her comeuppance in the end, it isn't as satisfying as it should be, since Meg ultimately dies from malnourishment and internal injuries. And when you learn The Girl Next Door is based on a real-life murder, you'll probably never want to think about it ever again.
