The imaginary must be imagined, accurately and with scrupulous consistency. A fantastic setting requires vivid and specific description; while characters may lose touch with their reality, the storyteller can’t.
Ursula Le Guin, review of The Buried Giant by Kazuo Ishiguro
Is there any more point to science fiction?
The history of a genre is driven in part by the dynamic between convention and invention; science fiction, though, seems to have an extra feature. Its USP is meant to be its inventiveness, assumed to be found in a given story’s idea or set of ideas. Fans believe that this is proof of the genre’s vitality as compared to others. Critics believe it’s an excuse for what they see as science fiction’s otherwise more general conventionality.
