 The film doesn’t use sound to telegraph its frights a mile away (there are no jump scares, here... well, maybe one), nor does it build its scenes around a single cheap thrill.On the contrary, this is horror filmmaking that’s designed to work on you like a virus, slowly incapacitating your defenses so it can build up and do some real damage.There’s a looseness here that’s missing from mainstream American horror, a sense that absolutely anything can happen next (and always does)."
