Fans of The Walking Dead and other “I’m an average Joe quarantined in the apocalypse. Get me out of here!” sagas would do well to stream this British remake of an earlier series about the scant survivors of a global virus and their attempt to reboot civilization. Luther fans may also appreciate the gripping, sinister turn by Nikki Amuka-Bird as Samantha Willis, England’s lone remaining government minister who gradually descends from communal leader to self-appointed autocrat and selective executioner. With one pull of the trigger on a harmless trespasser, Willis (who, unlike Walking Dead’s Governor, declines to even codify her supreme power with a title) sets a panicked, Darwinian precedent that echoes how people managed to evolve the first time only to stumble and self-destruct.
