I really dislike how the quick flashbacks were edited in this movie so I would just remove all of them, and remove Kylo’s appearance during Rey’s training because it only makes things confusing.
I didn’t really care one way or another about the style of it, it seemed fair enough for what they supposedly were - force induced flashbacks and flashforwards. It’s definitely a little problematic when it comes to the latter however because we don’t know what we’re looking at in such quick flashes.
It’s definitely the first part in the movie where I was thinking wow the editing is all over the place. The way I envision my Rey Nobody edit I think I’d need to keep Kylo in there to watch the vision as well, but I’d probably want to restructure how it plays out. Maybe cut out seeing Kylo taking out the mask and touching it? So we see Rey, we see her have a vision, and then we see Kylo’s having it too? I guess the problem with that is I think we’re supposed to believe Kylo is what distracts her and makes her start destroying trees and whatnot. I think you could probably solve this by hearing his voice say something like “Rey, join me” and then Rey trips.
