A small group of old school friends spend a boys' weekend at a remote forest cabin but when one of them, Tyler, scatters his dead mother's ashes a strange and magical corridor occurs in the snow. At first they see it as something incredible and weird but harmless. However things soon take a dark turn with them violently turning on one another with deadly results. This is a Canadian movie which sticks with metric measurements rather than trying to be "American", credit to them for that. It was shot in Nova Scotia during winter and the snow covered landscapes not only look good but also add to the sense of isolation and bleakness. The opening scene is quite horrific but then the rest of the first half is slow in terms of horror, though the characters were engaging enough to keep me interested. The vast majority of the horror comes in the second half. Gore highlights include a knife through a hand, a bloody garrotting, a scalping, a cruxifiction and several shootings, in the UK the violence got it a BBFC 18 certificate. The acting is OK but one of the guys has one of the funniest looking fake bold patches that I have ever seen, hilarious. The plot is quite original but sadly I failed to understand the confusing ending, if it wasn't for the funny bolding guy I'd have rated this a 4 but it gets an bonus point for the slaphead!
