Query: Boring!

I can't believe how disappointed I was in reading this book. It was boring and the style was incredibly poor. What is worse is that while it describes the Mayan ruins no photos are included. Wright has an infatuation with the Mayan calendar and numbering system but what would have been helpful is a clearer (like using the Gregorian calendar) picture of when events he tells of happened.
