No, mostly that's about genre because genres have definitions and expectations for content -- and audiences typically know this. That's why sci-fi aficionados generally make a beeline for the sci-fi section while generalist readers may stop first at the best-selling books display. When there is no general interest category it's because that's a given -- the subgroups, or genres, are the ones noted because they are the exceptions, not the rule.Sharr Khan said:
But there's a reason there's a separate section in the bookstore, video store, and many libraries that separate sci-fi from general interest
Mostly that's about categorization and ability to find what you want at the moment. "General interest" isn't a real category: it has Westerns, biographies, and historical fiction (and all the same rules apply to any kind of fiction), Fantasy, cook books.
If the story is good and is entertaining or holds some kind of artistic merit those not into "scifi" will go or "Star Wars", "ET" and "Close Encounters" wouldn't become iconic films.
At one point in time there wasn't a "Star Trek" to fit into any category and no fans of such - those fans had to come from someplace and don't doubt there are cross overs there since humans are by nature dynamic beings.

Works do crossover now, but they still tend to be identified for their primary intended audience. Thus a murder mystery that takes place aboard a futuristic spaceship isn't likely to be found in the mystery section but in the sci-fi section.
Movies tend to be grouped similarly. Want evidence? Where is the trailer for Star Trek going to be shown? Before Love in the Time of Cholera or Cloverfield?
