This week on Pop Culture Happy Hour, NPR Monkey See’s Linda Holmes, Stephen Thompson, Glen Weldon, and Kat Chow discuss the new Tina Fey comedy Unbreakable Kimmy Schmidt. They’ll talk about it’s extraordinary silliness, its employment of stereotypes, and that unforgettable theme music. Then they’ll try to find the solution to the problem of when culture that’s inspired by other work becomes what we derisively call “derivative,” whether it’s critters that look a lot like Hobbits or songs that sound like Iggy Pop. All that, plus What’s Making Us Happy this week.
