While it's entirely possible that Terry Pratchett simply isn't for you, just let me say that I'm a huge fan and The Colour of Magic sucks. Early Pratchett is all parody, and most of it is honestly pretty bad. It's well before Pratchett found his feet in the setting or defined his own voice, the characters are still very flat, and the humor is less character-based, somehow simultaneously less good-natured and less cutting, and not really in the vein of what he does best. In my opinion, he didn't really settle into the Pratchett I love until about 1991 with Reaper Man. The books before have their moments, but from that point on the kind of genius that has firmly set him in place as one of my favorite authors in any genre started to blossom. It's around the turn of the decade that he figured out how to do truly clever satire in concert with great storytelling rather than weak parody for its own sake. My personal favorite sub-series is the City Watch line. If you should ever decide to give Pratchett one last chance, I'd recommend reading Night Watch. Chronologically, it takes place fairly late in the City Watch line but stands alone pretty well, and is in my opinion his finest work period.I have a hard time finding anyone who does fantasy comedy well. I like Monty Python and OOTS, but most of what I've read in the way of fiction doesn't do much for me (as opposed to Douglas Adams, who I think was great). I've tried Pratchett. I tried to read The Colour of Magic when it first came out. I made it about forty pages in and threw the book aside. After being assured by friends that I was just the sort of person who'd like Pratchett, I've tried half a dozen of his other novels with the same result. Recently (a month ago), I tried The Colour of Magic one more time. I made it perhaps 60 pages.
As for my writing, I don't really think of it in terms of genre while writing. I have a strong tendency towards epic fantasy, though. My novel-in-progress is pretty squarely in the Sanderson camp of epic fantasy.
