Sleep: O Mal Nunca Dorme

It’s a horror movie about sleepwalking and the unquiet sleep of a fraught marriage, with hints of The Exorcist, Sleeping With the Enemy and Steven Soderbergh’s neglected Hitchcockian thriller Side Effects.

This is one of those horror films where the exploration of genuinely unsettling ideas is skilfully done throughout...

...Wu’s film does a fine job of toying with our expectations...

...it’s a fine-tuned (and eerie) marital drama where one partner suffers from a bad case of sleepwalking while the other worries about it, so it’s both a paranoid thriller and a slow-burning ghost story.

By keeping the horrors imaginative yet believable, we are made to participate in this psychological horror’s twists in sickness and in health, for better or worse.
