I liked Time Out's take on this book: "Wickedly funny". Neil Gaiman's twisted sense of humour together with sheer craziness of Terry Pratchett created this unique masterpiece. Only these two authors could put Antichrist, angels, demons, God, devil, witches, aliens, Atlantis and above all...Armageddon in one novel and make it seem like a normal thing. In fact these things together with footnotes full of confusing information make for entertaining experience. Some of the footnotes are even true (which makes me think that world is actually even more twisted than these two lunatics). Great read!
