I read your post through Planet Drupal this morning and found it pretty annoying. Imagine you wrote a book and someone said this about it, I bet you wouldn't be too happy. I got a book for free in exchange for a review and now its a doorstop, soon I'll get rid of it, LOL, look at me, I'm funny. I paid for this book and it looks pretty useful for the vast majority of Drupal users (read: not you). The documentation on theming on the site is pretty awful and as we all know, Drupal themes tend to be butt ugly compared to Joombla. Anyway, it sounds like you have never reviewed a book in your life before, but maybe you should think about the audience? I doubt the author wrote the book for you, but maybe you would be in a good position to evaluate whether the information in it is correct and if it paints a good picture on Drupal theming for the rest of us. But as an author of other books, I have to say, this was pretty insulting and if this was my book, I'd be ticked off at you.
