The Seminal Wilber IV Book

This book is really a conversation about Sex, Ecology, Spirituality.  It's the most often recommended Wilber book for newbies.  Yet, it wasn't really until reading SES that I learned the theory behind all the charts and diagrams that are presented in this book.  Or maybe I just read this one too fast. 

What did you all think of this book?  What did you like / dislike about it?  Do you think it lives up to the hype?  Is anything missing from it?

I'd love to hear your thoughts!
