They dressed me up like this. And this isn't my nose, it's a false one.
I have to say I'm not enamored of Discworld, either. I have been told that I picked the wrong books to start with, but when I challenge for a specific list of titles to go with, I get vague answers. It's not easy to go with vague information to a book store and pick up one book off the Pratchett shelves that's part of the arc that was recommended.
I started with a Rincewind book, and was terribly disappointed. Not sure I finished it before taking it to the used book store. There was nothing that Rincewind gave me that I hadn't already gotten from Robert Aspirin, Craig Shaw Gardener, or a handful of other fantasy humorists.
I guess I'll toss the gauntlet out to this esteemed group. What specific title would convert a non-believer into a Discworld fan? Just one title, as I am only willing to give Pratchett one more chance.
