I read the book a few years ago around it's initial release and I was an instant fan. When I found out they were making it a movie I truly could not wait. The film was amazing. It wasn't exactly like the book, but I didn't even care, it worked so well despite that. I probably cried 8 times (but I am an emotional person and a lot of the topics in the movie hit close to home so can't guarantee you'll have the same reaction). If I recall properly Bo & Willowdean's aspect of the story was a bit more present in the book, but I'd rather have less romance and more of the actual message & content if you were to change anything. All in all, it's a must-watch in my opinion. 9/10.
