With regard to pacing, I think the Pasana and Kijimi stuff could probably be condensed into one segment, which would free up 15 minutes or so that could be better spent restoring the Lando’s kidnapped child subplot and/or showing Rose’s study of the old Star Destroyer plans actually leading to some insight that helps in the battle. Or going into any amount of detail about how the Emperor came back. Or setting up the Force dyad, like, at all.
Make that Pasana and Endor and ditch the Kijimi stuff and Kylo’s command ship completely. Both the Pasana and Endor segments start with the gang hunting for an item and end with a Kylo confrontation. For a film that seems to have a lot to say it sure wastes a lot of time on dull repetition.
