I was hoping for wit and humor, unfortunately I was sadly disappointed. The book is so simple in tone, content and presentation, it could have been written as a high school essay. Moreover, it defies its own title--we may need to "blame" the author. There is nothing new in any of the arguments presented, and most are presented in a rather juvenile fashion. Reading a few Atheist Blogs and a listening to a few podcasts will provide as much, if not more information, and in a much more enjoyable manner than reading this book. The only thing preventing a one-star rating is the cost of the book (99 cents) and the potential benefit, even if ever so slight, of introducing the layperson to the bare-bones arguments against Christianity. Even then, it is almost useless because nothing is cited. No Bible verse or philosophical reference for the arguments is mentioned. If you have to bring up Godzilla in an argument to make a point, you have already lost your audience and you're dangerously close to losing the debate.
4/17/11 Update: An email prompted me to add a response to the question, "Why did I buy the book after reading the 'free sample' if it was so bad?" The answer is simple; I was hoping for more. If I could have written the book, which I could have, it does nothing to add to my understanding of the content. As I noted in the above review, it was only 99 cents so it was gamble, one that I lost.
