I finally got around to knocking out Reaper Man. Although I enjoyed it far more than the Rincewind stuff I had read before, it didn't convert me. It did more me from dislike to neutral, so that's something, I guess.
Well, semi-serious parody isn't necessarily to everyone's taste, and Lord knows Pratchett can be very British in his humor, which is also not to everyone's taste. It's not a failing to not love it.
It's a mortal sin.
I'm glad you liked Reaper Man more; if I knew exactly what you liked or didn't like about it, I might be able to recommend further reading more specifically.
