Crazy in love
Kudos for the CW's belief in "Crazy Ex-Girlfriend." Despite its status as prime time's lowest rated network series, the musical comedy has been renewed for a second season, ensuring its small but loyal fan base another round of eclectic, clever numbers that rival anything on Broadway that isn't featured in "Hamilton." Tony winner Lea Salonga shows her approval by popping by for this week's season finale.

"12 Monkeys," the TV adaptation of Terry Gilliam's 1995 film, returns for a second season of trying to save mankind from extinction — and, subsequently, a severe shortage of bananas. It appears as if the movie's star, Bruce Willis, is still too busy making "Die Hard XIII" to make a guest appearance.
