I was very, very torn on the very concept of this book. Coming from a protestant background and being a Christian myself, I was concerned that this book's purpose was to make an anti-religious statement, but I was entirely wrong. Yes this book may be considered controversial, as any book on religion is, but I found it very enjoyable. Gaiman + Pratchett stay away from considering the truthfulness of the religion completely, and tell the story from a unique and very...odd position. I found myself laughing at many of the situations, and really enjoyed the merge between reality and "what-if" fantasy. (the "other" Four horsemen FTW!)
