work in progress
I have a friend who makes a point of reading stories against the grain. If it's a comic book about a hero who catches thieves just like flies then he decides that the thieves are all heroic Jesse James types and the hero is a fascist oppressor. (OK: the idea that bankers and vigilantes are baddies may not be that much of a stretch.) If it's a story about heroic warriors fighting bug eyed monsters in space he recasts the bug-eyed monsters as oppressed colonial victims. I assume he thinks that Doctor Who is a racist: the Daleks are just misunderstood. Or possibly Doctor Who is just impossible to misread; which probably means it's not worth reading in the first place.
I can see how this game might keep an intelligent brain occupied while it's owner was watching movies about Cowboys and Indians and Cops and Robbers. (Perhaps if you are bright and creative enough to rewrite the film in you shouldn't be watching the Lone Ranger in the first place.) I would guess that it renders (for example) Watchmen practically un-watchable. The text already undercuts itself so radically that it's hard to see what is gained by a clever reader willfully subverting it. "Let's read Watchmen as if Rorschache is the good guy." Well, yes, the text positively encourages you do that. "Let's read it as if he's the bad guy." Yes, the text positively encourages you to do that as well.
On Lewis's terms, this sort of playful approach is the least "literary" imaginable. It is only interested in using the text as raw material for a game; anything that the actual author put onto the actual page is likely to disappear under the weight of subversion. Turning Star Wars (in your head) into a story in which Luke Skywalker is a religiously inspired terrorist is only one step up from school kids pretending there are dirty bits in Middlemarch. (Which is what they had do before the invention of the internet.) But can it really be that an active reading is worse than a passive one? Couldn't one equally make the case the kids comic annual that says "Look, space ships" and leaves the kid to do the actual imagining is one of the highest and most dynamic forms of literature. (It's also how good pornography works. So I'm told.)
If you are already taking the trouble to imagine that perfectly clean books are dirty ones; or of reading one novel and making up a different one in your head, then why not go the whole way, write your day-dream down on paper, and create completely new stories of your own? I suppose that's how Fanfic got started.
I don't think that a gay teenager, reading Legion of Superheroes and deciding that (I think it was) Bouncing Boy must be gay was consciously engaging in a subversive queer reading. I think that was a natural thing to do when there were no gay characters in comic books. The whole idea of Robin and Bucky was that you got to imagine that you were Captain America's or Batman's Very Special Friend. At one level, fan fiction writers are using popular fiction in the exact way it's always been used; in the exact way it's intended to be used. (Has any one ever read Harry Potter and not pretended that an Owl is about to drop a very important letter through their bedroom window? See also: Power Rings, Jaunting Belts, Light Sabers, Lenses...)
But it seems to be that when fan fiction becomes too much of a thing, the Legion and Harry Potter are basically reduced to a commodity: raw material to be chewed up and spat out and in new form, one where the baddie is the goodie and both of them are having kinky sex with each other. Which is fine. I mean, its fun, and its creative and its interactive and it doesn't do anyone any harm. I think it might be a pretty good working definition of the difference between a fan and a critic. A critic writes an essay about a book. A fan write three more chapters. (And then dresses up as the main character.)
But. There is Doctor Who fan fiction online before the closing credits of this weeks episode have been ruined by the continuity announcer. When Amazing Spider-Man 2 came to an end, I sat in the cinema for eight minutes to see if there was a post-cred. My fan-fic writing friends used those eight minutes to write a short story based on the premise that Aunt May was having an affair with Norman Osborne, and posted it to the internet before I left the cinema. They must literally sit through the actual movie thinking "What if this character were gay? What if I added a sex scene here? Could that background character be reimagined as the protagonist of the movie?" They have their reward. But this critic wonders if they can be said to have ever actually "seen" the movie they are writing about?
