The Perfect Novel?

At the New York Times books blog, PaperCuts, there's a heated comments-based discussion on whether such thing exists as "the perfect novel."

Is it The Great Gatsby?
Lolita?

I think I might be more on the side of "there's no such thing as perfect" -- but I'm willing to hear arguments. PaperCuts had 135 comments on the topic, last I checked -- and I'd wager there are more even now.
