I'm in a similar position, except I've already read The Colour of Money. And found it boring. The only cool part was when Death appeared for a page or two.
So I'm going to give the Discworld another shot with Mort. It's third or so on my (fiction) reading stack. We'll see how it goes.
But maybe Discworld simply isn't for me. After all, I wasn't fond of The Hitchhiker's Guide to the Galaxy either.
