Show of the week: Frontline: Facing Death

Today’s medical technology is better than ever at prolonging life—but at what cost and to what end? Those are questions Frontline confronts as it follows doctors, patients, and families inside the intensive-care unit of New York’s Mount Sinai Hospital. The wrenching choices the families face include whether to remove a loved one’s breathing tube and when to reject costly treatments that have minimal chance of success. Powerful and intimate, the documentary reveals the raw emotions behind the clinical facade of modern, “medicalized” death. Tuesday, Nov. 23, at 9 p.m., PBS; check local listings
