— It’s never really over. Ever since "Lost," television has ditched its sense of finality. Characters in the great French series "The Returned" come back from the dead, complicating the lives of their loved ones. Folks on "The Missing" never let go. The passengers on NBC’s "Manifest" checked out for years, only to return, trailing clouds of mystery.
Starting today, Amazon streams the eight-part British mystery "The Widow." Kate Beckinsale is Georgia Wells, a Welsh woman whose husband worked in some kind of NGO in Africa before he and hundreds of others apparently died in a plane crash in the Democratic Republic of the Congo.
A grieving Georgia has not left their shared mountain cabin for three years, and she’s a mess. Catching sight of a man who looks suspiciously like her husband on a television news report from the Congo, she decides to travel back to the place where he worked and reportedly died. There, she and the audience discover that he was not entirely honest with her about the nature of his "charity" work. The mystery deepens when a survivor of the plane crash, also reported dead, shows up in a Dutch hospital.
Look for Alex Kingston, ("ER," "A Discovery of Witches") as a colleague of Georgia’s husband eager to keep secrets. The always icy and ominous Charles Dance ("Game of Thrones") stars as a friend of Georgia’s father and a veteran of intelligence work, very eager to keep her away from asking too many questions. Supposedly for her own good.
Compelling and well-acted, "The Widow" makes the most of exotic settings, from lush Africa to austere Wales. All the same, it suffers from the chief affliction ailing Peak TV. A story like this used to unfold in three or four episodes on a "Masterpiece" presentation. "The Widow" asks viewers for eight hours of their time.
