H. Allen Orr reviews some god books including "The God Delusion" by Richars Dawkins here. It is a free access article. Orr is clearly disappointed.
In my opinion, H. Allen Orr is one of the best reviewers of science related books and has written some nice articles himself. Here is a link to some of his articles and reviews. Some more appeared in the New York Review of Books but not all of them are free access articles.
