You certainly do seem fond of him.
Have you read his recent chapbook, The Tain, by the way? I'm waiting to get a hold of the anthology Cities (Ed: Peter Crowther) which includes it, but it would be interesting to hear from someone who has read the story.
Interestingly, John Clute's review of Perdido Street Station actually has a long sequence where he shows how the book is SF, fantasy, steampunk, horror and so on, in turn. I guess Mieville's own classification, 'weird tales' is simpler to resort to!
Seriously, I don't see why SF and fantasy need to have such distinct lines drawn between them, and one of the things I like most about Mievile is that he seems to go ahead and tell his story, and describe his world, without worrying too much about about what the punters will classify it as.
