This week on Pop Culture Happy Hour, NPR Monkey See's Linda Holmes, Stephen Thompson, Glen Weldon, and Chris Klimek discuss Avengers: Age of Ultron, covering everything from the fighting, exploding, and if Thor is really necessary. Then they'll talk about pop culture pariahs: the bands that get no respect, movies that are shorthand for things that aren't cool, and even the selfie stick. All that, plus What's Making Us Happy.
