I have a few pet peeves.
– I really hate stories that revolve around wish fulfillment. This is because the result is usually not a story at all, because it lacks anything resembling conflict. I have this discussion with commissioners on occasion, where they ask me for a story, but it’s clear that they don’t actually *want* a story–they just want a 5000 word TF sequence. I mean, don’t get me wrong–I understand the desire there, and I see that as legitimate, but that’s not what I’m doing here. I’m not granting wishes, I’m writing stories.
– Clueless characters. Oh god, does this get my shit twisted up. Generally, this manifests as characters surprisingly not knowing key facts about their world, despite the fact that, having gotten as far as they have into the story, they would have been required to understand how the world functions. It’s super sloppy writing, and a signal that the author hasn’t really bothered to grapple with their characters as beings, as opposed to dolls.
Those are the big ones, I think. I’m sure there are others.
