Another new Brit horror movie, Steven Sheil’s first feature might well be described as the bastard offspring of Mike Leigh and Gaspar Noe one wag has already dubbed it The Royle Family meets The People Under the Stairs. Some suggest Mum & Dad parodies life in Thatcher’s Britain; others have drawn a parallel to recent shocking real-life events in Austria. However you see it, this is a thoroughly unpleasant viewing experience, and we mean that in the nicest possible sense. When young Polish cleaner Lena (Olga Fedori) is offered a bed for the night by amiable co-worker Birdie (Ainsley Howard), she finds herself trapped in suburban hell literally. Anybody with a healthy contempt for traditional family values should enjoy (if that’s the appropriate word) this blacker-than-black comedy.
