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?


I think, personally, its less about how hard or soft the sci-fi is and more about how fleshed out the sci and the fi is. Im a big fan of science coming into contact with the unexplained, in an Event Horizon or Doom 3 type of way. The audio logs and background stories of Doom 3 are fantastic and really makes the world feel real and fleshed out.
