Facebook is debuting its new streaming service — with a show about a grieving widow

“Sorry For Your Loss,” which will release four episodes to users next Tuesday, is set up with what seems like a mystery conceit. There is abundant use of flashbacks as star Elizabeth Olsen’s character, Leigh, remembers her husband (Mamoudou Athie, also at the Toronto event) and both questions and revels in her memories of him. Unlike a show such as TBS’s “Search Party,” which used an actual disappearance and manhunt in its first season to sustain interest in a young female character’s slow disappearance into herself, the only mystery here is whether Leigh really knew her husband, or herself. - Steven Zeitchik, Washington Post [via/web:http://streaming-tv.us]
