I didn't read the book, but I personally loved the show and the music. The chemistry between the characters was great and felt authentic. People are saying that the plot fell off when it should have gotten more intense, but the band ended abruptly and I think that was done intentionally. It was a choice that I think was meaningful and I really just loved it. I also loved the ending. It was very emotional and I really connected to the characters and it was the best show I have seen in a while.
