Query: mediocre ...at best

This book is not very good. Every word seems calculated and is technically "right" but I found myself not caring about these characters.There is a distinct lack of depth to these characters and we never get to see below the surface. Reading this book is like watching a talented boxer dance beautifully around the ring, but never throw a punch. Something seems to be missing. It moves along in an obvious way, sort of like a new TV show, and its structure is representative of what passes for art in the 21st century, but it left me cold. I want so much more than a tepid, quirky, cleverly concocted story like this. It seems to have been written with a particular audience and a particular batch of critics in mind. The overall tone of the book is very smug, while pretending not to be. I think Green has some talent, but I think he should stop writing what everybody wants him to write.
