i.e do you prefer:
- technically grounded and plausible science elements (e.g The Martian)
or
- stuff so fantastical that it doesn’t even warrant trying to explain it (Dr Who, some Marvel/DC stuff, Star Wars)
Another way to look at this would be Sci-Fi versus Science Fantasy, perhaps.
- Old-School Sci-Fi like HG Wells centers around a core scientific idea and the consequences arising from that,
whereas
- Science Fantasy (more prevalent nowadays) only looks to science - or the impression of some science - to serve the fantasy devices it uses.
So which is better?


Greebles, also called greeblies (singular: greebly)[1] or nurnies, are small relief details used to give visual complexity to a model. The act of decorating a model with greebles is known as greebling. While greebling originated as a technique in filmmaking, it is commonly used in model-making, toy design, and kitbashing. https://en.wikipedia.org/wiki/Greeble
I think the Expanse almost finds the perfect balance.
