Hmm. Very few "heck no!" votes besides mine. I shall have to explain.
First, if you could check more than one box, I'd also have checked that I only know his Lankhmar stuff. Just for the record. Also, if there had been a box between "heck no!" and "he's just okay," I'd have checked that.
Some of his early Lankhmar stories are actually pretty decent. About halfway through, though, the series really took a turn for the worse. And that final Lankhmar story--the one where Grey Mouser is trapped underground--is just about one of the worst pieces of poorly written, cheap softcore porn excuses for a fantasy story I have ever read in my life. Even if I'd thought the series was perfect up to that point--which I didn't--he'd have lost respect for that story alone.
Those of you who are just now picking these stories up, I suggest you stop at book three or four. You'll be a lot happier in the long run. (IMHO, of course.)
