Director Thomas Jakobsen, who co-wrote with Justin S. Monroe, stages such a basic Deliverance-style ordeal that it’s obvious the film is holding some cards back – and, in fact, the big reveal is slightly too guessable and risks losing a genre audience who still feel burned by the way April Fool’s Day turned out. However, the quartet of performances have enough depth and individuality – for once, the victims aren’t interchangeable – to hold the interest. And – to give the game away – the fact that this all turns out to be staged as a radical form of intervention sets up a subtler chill involving the familiar figure of the helpful, smiling yet unspeaking pick-up truck driver (Gary Kraus) who seems to save the lone survivor but then delivers him back to his tormentors. Here, the guy is theoretically benevolent, but like counsellor Richard (James C. Burns) he comes over as ambiguously menacing … and the reach of this program, as demonstrated by a mid-credits sequence that ties a major loose end, is almost not reassuring, with the ringing phone at the final fade-out suggesting that though Michael has purged some of his demons he might have undertaken some obligations which won’t be comfortable to fulfil. Odd-looking Turton makes the most of what might be a nondescript role, and is responsible for much of the sinister undertone.
