You've been hearing it for months—actually over a year: "Watch Crazy Ex-Girlfriend." Do you watch Crazy Ex-Girlfriend yet? No? What's wrong with you? You need reasons to? Fine.

Crazy Ex-Girlfriend, which enters its second season on Friday, Oct. 21, stars its co-creator Rachel Bloom as Rebecca Bunch, a lawyer who quit her high-paying job in New York to move to West Covina, California for Josh Chan (Vincent Rodriguez III). Yes, Rebecca has finally come to terms with the fact that she moved across the country for her childhood ex-boyfriend from camp. To quote the new season two theme song: "They say love makes you crazy, therefore you can't call her crazy. ‘Cause when you call her crazy, you're just calling her in love." She's not crazy, she's in love. But in love with whom? Somebody or an idea of somebody?
