I read this when it first came out, and I was only a teenager at the time. Decided to re-read it after binging the movies when they came out on Netflix. 

Through the lens of an adult, this book is... meh. There are some key points I really enjoyed mostly due to nostalgia, but overall the experience of re-reading it wasn't enjoyable. As an adult, I could see the red flags better, but otherwise, meh. It was okay. 

I wouldn't personally recommend reading this unless you read it like it's junk food - reality tv, celebrity gossip. Just understand that the relationships in this are... how do I put it? Do not use this series as a road map to find love.
