Really enjoyed reading this - thank you. I personally felt SW was being over-explained even as far back as ROTJ when incidental aliens were being given names (I preferred non-names like Hammerhead, Snaggletooth etc which left everything to my own imagination).
BTW the ‘Dreadnaugts firing on each other’ thing was done in ROTJ too. I dimly recall Lucas explaining it in a documentary (don’t remember which, sorry)…
Over-explanation of SW is one of the reasons I’m possibly the only person on earth who doesn’t like The Mandalorian.
