I know my brother watched it a couple years ago and said it was good.
I believe it's a couple being terrorized by teenagers and kids in the woods near "Eden Lake", but they're not wearing masks or anything like they did in The Strangers.
The thing that bugs me is that I obviously called you kermybutts before, and my iPhone remembers that, but it never autocorrects "fuck" for me. I'm constantly typo-ing "fuvk."
