"Severance" (not rated, 46-57 minutes per episode, Apple TV) This mesmerizing nine-episode sci-fi series revolves around Mark Scout (Adam Scott), leader of a team at Lumon Industries (the industry is never clearly identified), whose employees have undergone a severance procedure that surgically divides their memories between their work and personal lives, bringing a new (and increasingly unsettling) definition to the idea of work-life balance. With Patricia Arquette, Christopher Walken, John Turturro, Zach Cherry, Britt Lower; most episodes are directed by Ben Stiller.
