‘In a month, your mother will be giving birth to two children and one dog,’’ drones the father to his children in “Dogtooth.’’ They return his announcement with a kind of neutered joy. This is mildly amusing, scarcely accurate news, sandwiched among scenes of incest, miseducation, and inhumanity that would shatter the SPCA’s heart. The cat looked innocent to me, but nothing in this weird, watchable, blasé black comedy from Greece stays innocent for long.
Our introduction includes a trio of adultish siblings (Aggeliki Papoulia, Mary Tsoni, and Hristos Passalis) sitting around the family home listening to a recording that asserts that the word “sea’’ means “leather chair’’ and that an “excursion’’ is a strong flooring material. We never get an age for these three, but they look old enough to know that their legs are being pulled. In the next scene we meet their father, Christos Stergioglou. He’s driving a blindfolded security guard (Anna Kalaitzidou) to the house for her latest hired assignation with his son. In 10 minutes, we know this man has spent most of his paternity pulling legs.
