Bleakly funny surrealist satire about a well-to-do Greek couple who, for reasons unknown, keep their three grown children – two daughters, one son, all in their early twenties – prisoner in their pretty if isolated house. The "children" have spent their entire lives never having left the property, and the parents see to it that they have no knowledge of the outside world, even teaching them false definitions for alluring words such as "telephone" (a shaker of salt) and "sea" (a couch). Thus these three young adults are modern-day Kaspar Hausers, by turns infantile, petlike, and robotic.
Punctuated by moments of shocking violence and queasy sexuality, Dogtooth – the title refers to a myth the children believe that they will only be allowed to leave the premises once their right canine tooth falls out – definitely ain't for grandma. Lanthimos never explains why the parents have decided upon this draconian experiment, leaving interpretation open as to what his film is commenting on: child abuse, overprotective modern parenting, the tyranny of dictatorship, etc. What it does firmly suggest, however, is that rebellion is a natural human reaction against oppression, no matter how ignorant or fearful the oppressed. Which isn't to say that Dogtooth is an uplifting film in any way. But it is creepy, disturbing, bitterly comic, and highly original.
