Teen horror has a formula. A very simple formula of gory violence, schlocky dialogue, girls in lip gloss, boys in letterman jackets and plenty of grisly death. Scream clearly explained the rules, Tucker and Dale Vs Evil subverted them and, impeccably, The Cabin In The Woods broke them all. Until Dawn doesn’t want to break the rules in game form. It doesn’t have to. It knows they exist and it’s quite happy to introduce you to eight teenagers, pop them into the land of no cell phone reception up a snowy mountain and let you take it from there. And for the most part, that’s a bloody good thing. Pun totally intended.
