Bee-dubya-ell: As I said above, Mort and Reaper Man!

The Discworld of the earlier books is a very different place to that of the later ones, especially those featuring Sam Vimes (after the first one), where Ankh Morpork and its surrounds become much more like a very rough English county town with cosmopolitan additions than the sinister place of the early stories. In fact the "Discworldliness" becomes very diluted in those stories, and even more diluted in the "Younger Readers" witchy stories featuring Tiffany Aching, where it all gets a bit twee.

While I love TP, I think the last 8 or 10 books are nowhere near the quality of the earlier ones.
