At last, a British movie with a degree of ambition, even if the ambition remains unfulfilled by the film's fade-out. Basically, this is the old tale of the blocked male protagonist becoming enervated by an encounter with his dark side before ultimately realising the error of his ways (see also FIGHT CLUB). As a meditation on machismo and the male psyche, this certainly passes muster, with the dark side manifestation Billy (a truly scary and, hopefully, career-defining performance by Marc Warren) proving that the devil really does have all the best tunes (literally, as the soundtrack really rocks when the characters get down to their darker doings). However, the invention and insight runs out around the halfway mark leaving us with some sub-Georges Bataille musings and a conventional wrap-up which seriously detract from an interesting set-up which promises much but delivers merely a light cuff when a sucker punch is needed. Still, it's dark, challenging and occasionally disturbing work (the corruption of innocence theme is particularly well handled, as is the direction of all the child actors), and the explicit sexual detail will almost certainly result in a truncated or unrated version being released Stateside. On the basis of this, director Penny Woolcock and saturnine star Marc Warren look to be emergent talents well worth watching. Recommended, albeit with reservations.
