This isn’t something totally necessary, but I noticed two minor things that I thought could be easily fixed. Though I’m curious if anyone else noticed these, or thinks it even requires these additions.
When R2 is showing Luke the original hologram, Luke calls it a cheap move, then R2 turns to give Luke a look. It cuts back to Luke, who returns to watching the hologram, and it then cuts back to the hologram, which is in the same place as before, even though we didn’t see R2 turn his head back around. I think it would be nice if R2’s head motor-sound could be added during the Luke shot, implying R2 turned his head back around. Not at all necessary but I thought it’d be a nice touch.
A similar situation, when we are introduced to DJ, we first see him with his jacket collar popped up. In the next shot of him, though, it is popped down. Also not a big deal, but I thought one could add foley of folding leather or cloth in the inbetween shot of Finn & Rose to help with this.
I think at least adding the R2 sound would be simple enough, but then again maybe it would draw more attention to the continuity issues.
You have a keen eye! By the way, only douchebags pop up their collars, so that should have been a clue to Finn and Rose right there.
