“Too Much” Remixes the Rom-Com

Starting over in New York is a cliché for a reason; so is starting over by leaving it behind. Lena Dunham, who became the poster child for a certain kind of Brooklyn millennial during the run of her first series, “Girls,” recently reflected on her “breakup” with the city in this magazine. Now she’s returned to television with “Too Much,” a romantic comedy about rediscovering oneself by saying goodbye to all that. The show’s protagonist, Jess (Megan Stalter), has little reason to stick around. Her live-in boyfriend, Zev (Michael Zegen), has left her.
