I absolutely abhorred Tigana and because of that I've been afraid to pick up anything else by Kay.
Here is what I sent to a friend who had read it, when we were discussing it by e-mail:
I have this weird way of explaining which books I like. If I like a book, I am able to picture in my head the world as if through a video camera - it is gritty, real, it is like watching a movie or real life. Such works that I can do this with are Tolkien's and Martin's. Books I don't like, or don't like as much, I am only able to picture as if they were a cartoon. Everything has the quality of cell animation about it, and not photorealism. Books like that to me are anything by Brooks, Eddings, and Tigana.
