What I found in this book was something certainly unexpected.
I thought it would just be a coffee-table catalogue with episode reviews and character profiles, but instead it was that and much more. The book is made to look like a surveillance survey of the Sopranos family. It's pretty fun to read what the feds 'allegedly' think about some characters or events of the show, but what disturbed me was the fiction that was written there. Some facts are mere fantasies of the author and I don't think they are authorized by David Chase or anyone else from the creative team of the show.
So, it's a four-star book, still a good one.
