9. Eden Lake - Eden Lake (2008)
Eden Lake is one of those inviting and romantic backdrops for couples with its wooden setting and secluded location, offering a seemingly idealistic break. However that's only if you can potentially avoid confrontation with some of the most unpleasant local youths ever imaginable, whom of which are both sadistic and disobedient, even to the point of their willingness of mercilessly tying you up in barbed wire and pitilessly inflicting pain upon you. Distasteful as that predicament sounds, even if you're capable of evading the dehumanising horror and suffering at the hands of these teenagers who are oddly impervious and capable of overpowering you, it is best to take into account that their parents will likely to be equally as malicious when it comes to shielding the interests of their young at any cost.
Tip to survive: Endure the horrifying music.
