It’s easier to learn the technical skills required to shoot and put together a film than to expertly craft a story. This explains why dozens and dozens of suspense thrillers that lack actual thrills flood cinemas every year. They are, though, usually, at least shot well. So how Shut In managed to get a worldwide release presents a bigger mystery than its story, which, as is usual for the genre, puts a pretty woman in danger at the hands of a deranged male.

Following the vogue for moody, Nordic-inspired films, Shut In has psychiatrist Mary (Naomi Watts) trapped in a secluded house during a blizzard. She’s alone with her stepson, who’s been hooked up to a life-support system after surviving the car crash which killed his father. Someone is prowling around the house and making noises – is it the town’s missing nine-year-old child, or someone more sinister?

Viewers will crack the case after 30 minutes, but it takes Wilson (Oliver Platt), Mary’s friend and doctor, considerably longer. In fact, the story plays like a reject from a screenwriting class, and the direction, editing, and just about everything else are pallid and occasionally risible.
