AVClub: It’s rare that a show can fire on all cylinders, all the time. The bad news is that with “Josh and I Are Good People!,” Crazy Ex-Girlfriend didn’t. The good news is that, even when it’s not perfect, it’s still one of the funniest and most original things on TV. I don’t want to settle for a good episode of a show that has the potential to be great, but good is still good. And it was, as was star Rachel Bloom. Rebecca, however, is really, really not good.
