You undoubtedly still remember The Machinist (2004) and the delicious fright that Transsiberian (2008) gave you. And so you will unquestionably trust in the Connecticut filmmaker Brad Anderson. So get stuck into his latest film, in which Evil awaits in the hollow trunk of a tree growing in impure soil. Owain's dog, Pippin, senses it, but who in a horror film has ever taken notice of a labrador barking in the dark? No one. And that's the way it goes. The whole lot of them possessed, slashed with machetes, turned into vampires. Pippin bites Owen, who develops a ravenous thirst for blood. Mum (ex-alcoholic, etc.) knows how to get plasma. Yes, she's a nurse. Yes, that lady is dying. Yes, it will give you the creeps.
