Realism is for lazy-minded, semi-educated people whose atrophied imagination allows them to appreciate only the most limited and convention subject matter. Re-Fi is a repetitive genre written by unimaginative hacks who rely on mere mimesis. If they had any self-respect they'd be writing memoir, but they're too lazy to fact-check. Of course I never read Re-Fi. But the kids keep bringing home these garish realistic novels and talking about them, so I know that it's an incredibly narrow genre, completely centered on one species, full of worn-out cliches and predictable situations--the quest for the father, mother-bashing, obsessive male lust, dysfunctional suburban families, etc., etc. All it's good for is being made into mass-market movies. Given its old-fashioned means and limited subject matter, realism is quite incapable of describing the complexity of contemporary experience.
