Sort of what you'd get if you took SILENCE OF THE LAMBS and cross-bred it with Neil Jordan's IN DREAMS. Going for a Lynchian feel, director Reynolds owes more to the spookily dreamlike imagery evoked by the writings of Ramsey Campbell. Images make you queasy, disturb and profoundly frighten you, yet you can't seem to quite tear yourself away from them, as if you're having a nightmare with your eyes wide open.
As singled out in other reviews here, Paolo Rotundo manages to temper the character of Simon with a sense of humanity, something you'd never dream of associating with a serial killer. This hearkens back to earlier little diamonds-in-the-rough from Down Under, like Richard Franklin's ROAD GAMES, David Blyth's DEATH WARMED UP or the more fantasy-oriented films of Peter Weir like THE LAST WAVE or PICNIC AT HANGING ROCK.
Like SE7EN before it, it disturbs and disorients you on some pretty deep levels, then gut-punches you with a shockingly unexpected ending, which may not make it something you want to see over and over again. But for fans of this particular genre, it's definitely worth a look.
