Hideo Nakata, Japan's master of suspense and unease, knocks one out of the park again with this follow-up to his Ring cycle. A neurotic single mother discovers a ghostly rising damp problem in the apartment block she moves in to with her little girl. Gradually, her sanity begins to ebb away. A squelchy study in female hysteria and maternal anxiety, yes, but also a good, old-fashioned spook flick.
