Have 3 different directors but have a general outline for all 3 that each director agrees on. Or at least have them be all of a piece and not stand alones, or a duology and one standalone. I’m not gonna single out Rian, the trilogy would have been better if Duel of the Fates was made. Because you would have had 3 distinct visions. They course corrected too hard on 9 and if that Rey movie is made they have to deal with the consequences of that.
The Mini Death Star canon was a neat idea like a mini nuke and totally believable. Starkiller base was just another death star, and Star Destroyer death stars was ridiculous maybe one Super Destroyer or two might have one but a whole fleet, not believable.
