Offering yet further proof that the future of cutting-edge horror is female, British actor turned writer-director Romola Garai’s impressive feature debut, which won enthusiastic applause at FrightFest last year, is a moody, brooding chiller that goes from slow-boil creaks to rapturous, hallucinogenic madness. Set largely in a decrepit building whose mouldy walls mirror a creeping moral malaise within, Amulet plays adventurously with subversive sexual politics and reconfigured horror tropes, conjuring a heady parable rich in ritual and intrigue, built upon sturdy subtextual foundations.
