Alright, Star Wars question, WRT the new trilogy,
you’re forgetting that nerds care too much about worldbuilding, so now the #woke thing to do is worldbuild like you’re fucking Akira Toriyama, and only assert things into being in your world the moment you need them without ever thinking for a second on how they fit into a coherent whole.
Broader cultural grumbles aside, it does seem clear that the makers of the new Star Wars trilogy were not thinking even for a moment about coherent worldbuilding. They were thinking “above all things we don’t want people to hate our work like they hated the prequels,” which led to “we need to make 100% sure that our movies capture that Original Trilogy magic,” which led to “we need our movies to feel exactly like the Original Trilogy,” which led to “we need a gritty scrappy Rebellion and a shiny all-powerful Nazi-coded Empire and an Episode 7 that matches the plot of A New Hope beat-for-beat.” And all else was sacrificed to this logic.
…in fairness, it’s not like the makers of Star Wars movies were ever thinking about coherent worldbuilding. That was left to the nerds toiling away on the EU.
It turns out that people are terrible at thinking about logistics and scale. So almost all science fiction (and epic fantasy and any literature set in a made-up world) has terribly incoherent scale problems.
You can see this famously in Asimov's Trantor, an entire planet covered in dense city skyscrapers, with a population of almost a billion people.
You can see this in Rowling's Hogwarts, which just isn't big enough to support the British wizarding community we see, and yet clearly states that almost all British wizards study at Hogwarts. (Let alone the idea that Rowling was thinking of Hogwarts as having nearly a thousand students, while setting a class size of forty).
You can see this in the Star Wars prequels, which announce a cloned Grand Army of the Galactic Republic which will have over a million troops.
You can see this in epic fantasy battle scenes of all sorts, where both the relative and absolute sizes of armies seem to change from scene to scene to justify whatever dramatic or narrative point the author wants to make at the time.
Now some authors mostly have a decent sense of scale. This tends to stem from authors who take this as a point of pride and actually literally crunch numbers for most of what they do. It rarely happens automatically.
(Sanderson is pretty good about this, probably partly because he has an assistant whose job is to check that sort of thing. A lot of the Serious Hard Sci-Fi is like that; A Mote in God's Eye for instance seems pretty good to me. Howard Taylor of Schlock Mercenary is surprisingly solid at this for a light webcomic. But he also dismisses the implications of his scale sometimeswhen it makes for a better joke).
So yes. The logistical and strategic background of the new Star Wars movies makes no sense. The scale of the conflict makes no sense. But it's not that much worse than everything fucking else.
