This book can be analyzed from various points. Previous reviews have had the philosophical approach that I am not enough prepared to discuss. What I can give is a "educated" opinion, although not trained one in the subject. I like the book. It was easy to read nevertheless the complex and some time hard to follow arguments. According to others reviews the book has not all the "right" arguments or the more accepted. I can't judge that But I can say that It is a open minder book. It present many of the arguments/propositions/"proves" in a general and clear view that can help to many people to see or at least to "think" in the subject in a most rational and logical way.
It is true that is open to reader accept some of the argument although the intention of the book was in many, if not all the cases, to prove the failure in the argument pro-god. The point is that Everitt does it without critics, in a fair way, and probably in an easy way to understand for many people in most part of the book.
Definitely this book is not for fanatics, but It can be for a religious person with an open mind.
