I feel like it was probably the fans that pushed the designs in the more realistic direction. You’ve got hyper-vigilant fans looking over every fucking frame in a show/movie, taking measurements, making calculations, writing to the network/studio, asking obscure questions at conventions, and not to mention many may be somewhat well-educated, it’s just gradually pushed modern designs in that direction. When I see all the little details in a show like The Expanse, it feels real and I appreciate the attention to detail.
When something seemingly awkward happens on-screen, like a spaceship doesn’t stop on a time, or their boots are magnetic because antigravity isn’t a thing, or whatever, and then you have to think about it for a moment, like, “Oh, that’s because of XYZ, now that makes sense!” I like those little moments.
