The MFA program did one great thing for me: It taught me how to be a better reader and critic. Nothing I wrote during my time at Columbia remains - but learning how to really deconstruct a work of fiction - that, of course, is a permanent part of me now.
The average detective story is probably no worse than the average novel, but you never see the average novel. It doesn't get published. The average -- or only slightly above average -- detective story does.... Whereas the good novel is not at all the same kind of book as the bad novel. It is about entirely different things. But the good detective story and the bad detective story are about exactly the same things, and they are about them in very much the same way.
The test of any good fiction is that you should care something for the characters; the good to succeed, the bad to fail. The trouble with most fiction is that you want them all to land in hell, together, as quickly as possible.
Most science fiction, quite frankly, is silly nonsense.
A lot of fiction doesn't answer a question that any reasonable person would ever ask.
I don't read 'genre' fiction if that means novels with lots of killing and shooting. Even Cormac McCarthy's 'No Country for Old Men' seemed pretty childish in that regard.
I am constantly getting letters from inconsistancies in the back stories of these characters.
I am not a fan of historical fiction that is sloppy in its research or is dishonest about the real history.
I am generally wary of the demand for 'likeability' in fiction, which I think is a bastardisation of the demand of identification - itself something of a suspect notion.
Critics have been amusing themselves for a long time by auscultating fiction for signs of heart failure.
