(It was seven points not 15 but here.)
I saw the musical, Dear Evan Hansen which was wonderful. The main difference between the musical and book was that in the book, Conner has a boyfriend who is spoken too by Evan. While in the play, there is no boyfriend at all. The book expressed emotion to the point that a reader can understand what each character was while the musical can vocalize and express those emotions. Personally, I would read the book again as well as see the show again!
