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.
I actually dropped it a few episodes in due to the extreme shaky-cam space battle scenes. Every once in a while I'd reconsider watching it but the things I kept hearing didn't seem compelling, and then after I heard how it ended I was very glad I'd made the choice to stay away.
I guess this leads to another "trope" (I don't know if it's really a trope so much as it is bad planning) where a series is advertised as having a grand story arc or deep mystery that's unfolding as the series progresses. I've been burned by these so often that even though I love that sort of thing I now take it as a signal to avoid the series until it's well and truly finished so I can find out whether the showrunners really did have that or if they were just lying through their teeth to keep viewers engaged.
