ROFLMAO
Ex-catholic myself - the nuns put me right off it, though none were quite as bad as Vorbis of course, which may make him/his role a parody too, but also a grotesque and thus satirical?
And yet I still feel a twinge of sympathy for him all the way through the book. Anyone with a decent imagination can lampoon fairy tales I would argue in this case and, as Terry is one of, if not the best satirist in the business, of course WA is brilliant (as I already said). But it's not a better story than SG, because it is piggybacking on existing and well-known (and therefore easy) story forms.
Any writer who can make the most vile of villains pitiable is at the top of their game and Terry manages it every time (well mostly - nobody's perfect). I love both books, but SG is the deeper and more skilfully written - why? Did Terry get Fatwah'd for it (remember Omnia is a desert country and Om is a desert god and not into turning the other cheek...)? Did the Vatican scream in outrage? Was the book burnt by the Klu Klux Klan? No. (And I am aware that Discworld is probably beneath the notice of said rigid bombasts and pedants so the fact that SG went beneath the radar is not really too surprising - but that says more for their ignorance and lack of vision than Terry's popularity and influence)
Best book. Definitely.
