LOS ANGELES — It may be the last day of September, but here in a middle-class, suburban enclave where the new CW show “Crazy Ex-Girlfriend” is filming, it’s Thanksgiving. One at which a Nicki Minaj-style song just broke out.

Perched primly on a divan between the Filipino parents of her former boyfriend — she ditched her job as a lawyer and moved across the country in a Hail Mary attempt to win him back — Rebecca Bunch (Rachel Bloom) does her best to woo them.

She’s already presented them with her homemade dinuguan, a Filipino stew. Now she bombastically spits out some lyrics from “I Give Good Parent”: “Your home is such a beautiful, comfortable space/ Bitches, you two have wonderful taste.”

In a season in which the offerings from the broadcast networks seem more formulaic than ever, “Crazy Ex-Girlfriend” decidedly stands out. Spurned by Showtime before landing at the CW, it is a full-fledged musical, veering across genres from R&B to country, as it integrates two to three original numbers into every hourlong episode.
