This parodically retro thriller from You're Next writer/director team Adam Wingard and Simon Barrett comes on like a cross between Fright Night and The Stepfather, although Wingard cites The Terminator and "an idealised synthy John Carpenter 80s wonderland where it's always Halloween" as primary influences. Downton Abbey's Dan Stevens sheds the tweeds as dazzling US soldier David, returning from the Middle East to turn his clearly cracked special ops charm on the family of a deceased veteran with whom he served. Despite initial suspicion, the family take David in, allowing him to fill the gaping hole in their lives. But when local townsfolk start turning up dead, Maika Monroe's gothy Anna begins to suspect that David isn't quite as attractive as he seems. Playing to a more mainstream audience than their previous outings, Wingard and Barrett's increasingly ludicrous schlocker has plenty of fun with genre convention, unafraid to laugh at itself as the bodies pile up and the knowing nods and winks become manic twitches. As we move toward a Funhouse-style third act, the tension dissolves into goofy gory chills, with Stevens chewing the scenery as formulaic madness reigns. The result lacks the vicious bite of You're Next (which was too nasty for mainstream tastes) and will doubtless do all the better for it.
