Before watching the show, I read the book, and it was fantastic. I loved it, hell, I'd even consider it the most well paced, exciting, and enjoyable books I've ever read, and I was really excited to watch the show. But the first episode alone was the most painful 50 minutes of my life. Within those 50 minutes, they made changes to it that really irritated me. Like making Tony talk to Clay earlier on about the tapes made no sense. And the time line is broken, and it would've been better if they had it take place over the course of one night, and have a big conflict and the end or something. I can relate this to a time where a movie was made out of a book, and may have even been better than the book: The Shinning. The Shinning is one of my favorite movies of all time. And yes, they made several changes to it such as Wendy's hair color, their car, and getting rid of some scenes that may have been important. But what The Shinning does good that 13 Reasons Why(The show) fails at is that The Shinning doesn't ruin all the characters(As a matter of fact, they brought them to life perfectly). In the book, Clay is a popular and well known for being a nice kid, making it interesting as popular kid realizes his flaws and betters himself. He and Hannah never had any conflicts except for at the party, but in the show he was mean to her a few times, and is socially awkward(Not sure how that adds to the series, but okay). A few other characters that were ruined were Tony and Hannah, and it's just a total mess. Yes watch it if you haven't read the book, because that way it won't ruin it for you, But if you read the book and enjoyed, avoid 13 Reasons Why at all costs.
