The Leftovers (2014)

Two per cent of the world's population simply vanishes, and the show never explains why. Damon Lindelof and Tom Perrotta follow the people left behind, Justin Theroux's police chief and Carrie Coon's bereaved mother among them, as they build cults, faiths and fragile routines around a loss with no answer. Be honest with yourself about the first season, which is relentlessly bleak; the second and third are among the best television of the decade.
