This week on Pop Culture Happy Hour, NPR Monkey See’s Linda Holmes, Stephen Thompson and Glen Weldon are joined by NPR Code Switch’s Kat Chow to talk about film ratings. What’s the function of film ratings—and do they actually work? The gang decided no to see the new film “Into the Storm,” but they couldn’t pass up the opportunity to talk about some of their favorite disaster movies. All that plus What’s Making Us Happy this week.
