“I Am Mother” (*1/2 out of four) was a dreary, derivative Netflix sci/fi thriller about a teenage girl (Clara Rugaard) who is raised in an underground bunker by a robotic mother (voiced by Rose Byrne) to repopulate Earth after mankind has become extinct. When a visiting stranger (Hilary Swank) informs her of a dark secret, she begins to question her identity and all that she has been told and taught in life. Film opens promisingly but soon grinds to a halt, as it becomes molasses-moving and tedious. Yet another futuristic thriller that owes an obvious debt to Stanley Kubrick and James Cameron but falters by comparison. Steve Annis’ shimmering cinematography is film’s only virtue.
