This entire film is in the shadow of uncertainty and approaching dread. It almost plays with the tone of a horror story. Olivia Colman and Dakota Johnson both play mothers who doubt their skill, desire and devotion to the role. Director, Maggie Gyllenhaal, takes on a complex narrative, filled with ambiguity, with her debut stint behind the camera. She nails it. "The Lost Daughter" is a masterclass of Hitchcockian tension.
