?Dear Evan Hansen? is a cultural phenomenon. Few Broadway musicals in recent memory have achieved such a far-reaching impact across a diverse array of audiences. It?s a show that brings people together from all walks of life, and provides a poignant commentary that rings cuttingly for the digital age. And the hype surrounding it just keeps building ? even receiving a shoutout in the most recent season of cult television show ?RuPaul?s Drag Race.? ?It?s been something that really kind of caught us all by surprise, to be honest,? Steven Levenson, who wrote the book for ?Dear Evan Hansen,? told HuffPost.
