A few examples:

* Slow, thoughtful, hard sci-fi that's well-written and well acted, with immersive (not campy) sets and effects. Enough of that to fill an evening a week.

* A spiritual successor to Firefly with the same production requirements and release schedule described above.

Even YouTube is bound by the same limitations as the AAA streaming platforms are—you can't sink money into something that's too niche, and right now doing things well costs buckets of money. So I'm sure there are a few fan films on YouTube adjacent to my interests, but their production value is going to be far below what it could be if things were made cheaper.

Yeah afaik Firefly didn't make money even back then. In 2-10 years the tech might be there for this, but it's not there yet.

If you're looking for hard sci fi I really recommend Andor.
