Writer/director Adam Green has made quite a name for himself among the genre in a mere handful of years. Debuting with the gory throwback slasher Hatchet, then the mind-bending thriller Spiral a year later. He has returned once again with the psychological survival pic Frozen, a film that I wasn't quite sure what to expect from going in. Surprisingly, the movie turned out to be quite a treat, despite the fact that it simply follows three characters and primarily takes place on a ski lift.
