What’s Streaming

CRAZY EX-GIRLFRIEND on Amazon, iTunes and Netflix. Season 2 begins on Oct. 21 — just enough time for a first-season refresher on this musical comedy about Rebecca Bunch (a Golden Globe-winning Rachel Bloom), a miserable corporate lawyer in Manhattan, who runs into a hunky summer-camp crush (Vincent Rodriguez III) just as she’s agonizing over accepting a promotion. He’s about to move back home to West Covina, Calif., and as fast as you can say case closed, she quits her job and follows him. Only he doesn’t know. More “Avenue Q” than “42nd Street,” James Poniewozik wrote in The New York Times, “this is a show about willing yourself, even past reason, to hope.”

LOVE on Netflix. Mickey (Gillian Jacobs), a self-help radio show producer with self-destructive tendencies, and Gus (Paul Rust), a dweeby aspiring screenwriter and tutor for a child star, connect cute and then try to decide if they’re meant to be together or apart, over and over again — until finally it dawns on them. She thinks dating a “nice guy” will help her get her life together; he thinks seeing a woman so erratic makes him appear more dangerous. “Sometimes, ‘Love’ suggests, romance doesn’t need candlelight to grow so much as an honest fluorescent glare,” James Poniewozik wrote in The Times.
