The only new show to make it to my DVR series list is "Crazy Ex-Girlfriend," co-created by its sensationally talented star, Rachel Bloom. Each episode is a full-on original musical that takes place mostly inside the head of its slightly demented heroine, Rebecca, a Harvard and Yale-educated lawyer who walked away from her type-A career in a New York City law firm to move to West Covina, California, where her boyfriend from summer camp lives.
