I've read five or six Pratchetts now. I must admit, I much prefer his earlier work. The Discworld series has become too self-indulgent for my liking now. I find that plot plays second fiddle to Pratchett's concepts, and as a result the books have become slow to read. I like his humour and his skewed notions on life, but, all said, I read for a story, which is lacking more often now.
