Query: It didn't add much....

As a long-time fan of this genre, I expected more from this book. However, it was too academic, spent too long on only a few authors and didn't add anything to my understanding. The author spent quite a bit of time reviewing plot details and I admit that I enjoyed her analysis of Nora Roberts and Jayne Krentz books that I had read, but there was too much detail and repetition.There must be better books out there....and I'd love to read any suggestions.
