I do not mean to say other genres suck or are inferior. I mean only to celebrate what I love in my own field, shameless optimist that I am.
Science Fiction. Fantasy. Alternate History. Together, these genres form the pillars of what is called speculative fiction. There can be lots of blending and subgenres that don’t quite belong to any one group (just look at steampunk and dystopia), but together they give an image of worlds that, as far as we know, don’t exist. Yet that’s not all they do. They can accommodate any other theme or motif, perform any other task, that characterizes fiction of other stripes.
Speculative fiction is a field of storytelling that specializes in “What if?” and “Why not?” It probes, challenges, questions, and explores in ways that no other kind of fiction is capable of. Yet it can take whatever has been produced by other sorts of fiction and give it more flavor, more chances for originality and finding what has been overlooked. Science fiction can probe as deeply into human nature as any literary novel you can think of. Alternate history can be as pulse-pounding as any spy thriller, or as romantic as a bodice-ripper from the checkout line. A fantasy can be a murder mystery, or even a slice-of-life tale (though it may be a slice of life from a magic student or an apprentice dragon-breeder).
Admittedly, there is a reputation which says speculative novels are not as introspective or deep or profound as “literary” novels. There are indeed thousands of shallow, hackneyed tales in all three genres, with little thought behind them.
However, one-dimensional stories do not remove the capacity for profundity or depth from any genre. Though fantasy may have its Twilights and Eragons, it also has its Name of the Wind and Song of Ice and Fire. Science fiction may allow The Fifth Element or Transformers into its ranks, but it boasts of Star Trek, Fahrenheit 451, and Dune. A million terrible novels could not extinguish even one book that doesn’t just ask “What if?” but also provides the best answer it possibly can.
I think bad fiction is usually bad because of untapped potential. The writer did not squeeze hard enough, or didn’t look in enough shadowy corners, to see what could nourish their characters, story progression, pacing, or anything else writers need to consider about their work. But when they do, they should be recognized for their incredible achievement.
In summary, this is why I love to read and write speculative fiction: It can always find a new place to go, and there’s nothing other fiction does that it cannot do.
