Replete with superb performances led by a paranoid Sackhoff and unhinged Cochrane, it's the rare horror film to know how to tease malevolent mysteries and deliver satisfyingly unexpected, unsettling payoffs.
It's easily the scariest movie since "The Conjuring," and in some ways is a deeper and more satisfying film. It's stylish but not showy, more concerned with the thematic undercurrents coursing just beneath the surface.
