Out on DVD now is  Prime Suspect: The Complete Collection, a truly great box set of the groundbreaking British TV show created by Lynda La Plante. An electrifying Helen Mirren stars as the flawed but fascinating Scotland Yard chief inspector Jane Tennison. All seven seasons are layered with tension and intelligence as Tennison solves crimes and battles her demons, particularly with alcohol. Prime Suspect was a dream marriage of show and star that each elevated the other's success. No wonder the American TV remake has stalled at the gate -- where is there an American version of Helen Mirren? Forget it. We're living in a golden age of television drama and Prime Suspect was a forerunner of a series that evolved with dizzying intelligence and gritty complexity.
