A minor continuity error I noticed is when Poe is speaking with Holdo for the first time. She says “It’s commander right? Wasn’t it Leia’s last official act of command to demote you? For your Dreadnought plan?”, but that wasn’t Leia’s last official act of command. Right before the bridge explodes she orders The Raddus to stay out of range of the First Order’s barrage and to have maximum rear shields or something like that. I know it could be explained that Holdo just forgot, but the order that’s keeping everyone alive seems like a pretty massive point to forget.
That line was especially annoying. A good leader shouldn’t be passive aggressive.
