On narrative consistency, and the dreaded continuity errors
of the science fiction and fantasy genres, an essay of nearly academic standards:
For you see, any story must have a certain amount of internal coherence if we are to achieve suspension of disbelief. And we must achieve suspension of disbelief. For most people, that just means that a given fictional universe must hold together for the space of two hours: if the main character in a conventional romantic comedy, possibly some movie for girls featuring Meg Ryan or someone like that, says at the beginning that she is an only child, she should not have a sister present at her wedding at the end of the movie. [...]
Yet sometimes the editors and writers responsible for such series barely care about maintaining continuity, so busy are they with more mundane tasks such as writing entertaining dialogue and coming up with interesting new characters. That is why such universes desperately need the obsessive, crank-like fan, the fan willing to concoct rationalizations that make sense of the apparent continuity errors. Indeed, without such fans, I question whether the continuity of these universes could be maintained at all. The fate of entire fictional worlds, the very cohesion of the space-time continuum, hinges on the selfless efforts of fans like myself to keep track of what the hell is going on and explain the slip-ups by the so-called “professionals”!
Yeah, that's the ticket; the writers and producers need us obsessive types. It's almost a symbiotic relationship, see. Or it would be, except for the tendency - even when die-hard fans alone become the entire audience - to spurn them in favour of "real" viewers. Sometimes it's tough being a genre fan.
