Chicago Reader review:
A lesbian love triangle becomes a schema of sexual power plays in Rainer Werner Fassbinder's most harshly stylized and perhaps most significant film (1972). The action is confined to a single set—the apartment of fashion designer Margit Carstensen, decorated with desiccated mannequins and a mammoth painting of fleshy, galloping nudes—where the three characters (one is a mute) scheme, complain, and attempt to seduce. With Irm Hermann and Hanna Schygulla.
