The long wait to see Karyn Kusama back behind the camera of a feature film is finally over, following up Jennifer’s Body with her cutthroat, paranoid thriller The Invitation. Calculated, tense and unflinching in its brutality, it’s a terrific simmering style of storytelling that boils into one insanity-fueled finish. In it, while attending a dinner party at his former home, a man thinks his ex-wife and her new husband have sinister intentions for their guests.
