A hyper-stylized mixture of physical violence and verbal comedy, Dogtooth, directed by Yorgos Lanthimos, is a darkly funny look at three teenagers confined to their parents’ isolated country estate and kept under strict rule and regimen — an inscrutable scenario that suggests a warped experiment in social conditioning and control. Terrorized into submission by their father, the children spend their days devising their own games and learning an invented vocabulary (a salt shaker is a “telephone,” an armchair is “the sea”) — until a trusted outsider, brought in to satisfy the son’s libidinal urges, plans the seeds of rebellion by trading VHS tapes for sexual favors.
