At times the plot teasingly recalls Joseph Losey's The Servant and Pier Paolo Pasoloni’s Theorem , poison-tipped parables about cunning social outcasts staging stealth home invasions against upper-class hosts.
Taking cues from classics of domestic intrigue such as Kim Ki-young’s “The Housemaid” (1960) and Joseph Losey’s “The Servant” (1963), they send this domestic drama vaulting into satire, suspense, terror and full-blown tragedy.
