“Counterpart,” Starz, Sunday, 9 p.m. (CRITICS’ PICK)

This smart and stylish drama is likely to please anyone who enjoys spy thrillers, the work of J.K. Simmons and Olivia Williams, or the sequence of celebrated dual-universe “Fringe” episodes that aired several years ago. “Counterpart” leans much more on espionage and thriller conventions than science fiction tropes, but it does use the idea of the existence of a parallel universe to explore ideas about identity, possibility and connection. It’s an efficient and entertaining show, and it’s a terrific showcase for its entire cast, especially the versatile and brilliant Simmons.
