Love them or hate them there are a lot of common tropes across the science fiction genre. What are some of your favorite and least favorite tropes?
I think it goes without saying that one of the least favorite tropes is Deux ex Machina. I couldn't quite put my finger on it at first, but after watching the German TV show "Dark" I was utterly dissatisfied with it. The entire series up until the very last episode is about this inescapable time loop and alternative universes which is pretty cool while watching it, but then you get closer and closer to the end wondering how they are going to solve this impossible problem. Then surprise they just do it instantly in the last episode.
Another trope I am not very fond of is nanotechnology where there are trillions of tiny robots that can effectively act as magic. It just feels like a lazy way to write science fiction because you really want a fantasy.
A trope I do actually like despite how overdone it is, is the idea of a precursor or forerunner. It often brings to light the absolutely massive scale of the universe which I find fun to think about.
This is maybe only tangentially related, but my most hated recent trend in genre fiction is "Your Fantasy story is actually Sci-Fi".
Numenara/The Ninth World is probably the most popular example (and I almost give it a pass for ingenuity), but it seems to be the go-to for trashy low-budget fantasy and webcomics; and it's also really popular in fan theories (Game of Thrones and AtlA being big examples). And there's always media that sort of straddles the line between the two (the new She-Ra: Princesses of Power show being an example; fantasy themes, sci-fi setting).
Of course, you could say the same thing about Star Wars. But I guess the difference, to me, is that Star Wars is unabashedly Sci-Fi. She-Ra tries to hide its Science Fiction behind of veneer of Princesses and pseudo-magical superpowers.
Agreed completely.
