Rose Byrne dominates in Mary Bronstein’s psychologically oppressive and compulsively dark story of a mother firmly on the edge. Both the actress and director take no prisoners as Linda (Byrne) appears in a cacophony of demands on her time as a wife, mother and (a barely functioning) therapist. Her sickly daughter is never seen, only a barrage of requests are heard, compounded by the ceiling that has caved in on her apartment, forcing Linda to move to a motel as her long-distance husband occasionally dials in. And one of her patients has disappeared. While the stress ramps up on screen, there is a catharsis to it all. Watch out for a deft cameo from A$AP Rocky.
