So how would I edit them? Eh ...
The three best things in the trilogy are, in order (and IMO) Ren, Rey, and the overall themes in the TLJ. I don't think that there are particular, or easy, cuts that can be made.
While we disagree over the quality of the movies, I think we agree over the essential facts. From the standpoint of direction and cinematography, they are competently made movies - much more so than the prequels, which brought out Lucas's weakness as a director, especially when trying to deal with the newness of making a movie mostly in CGI (which now has been around enough that the good directors have a good handle on it). And secondly, I agree with you over the essential strength of Ren, Rey, their relationships (to each other and to those around them) and that at least some of the themes introduced in TLJ were well worth exploring - even as much as I disagree over how well they were explored or in which direction they were taken.
And I agree with you that there isn't an easy edit to make it all right. I just got back from watching 'Knives Out', and the writing was so tight with barely a wasted line and not a wasted scene in the whole script and everything neatly constructed and working toward it's goals. Everyone in the fam loved it - the ones surprised by the twists loved it, and the ones like me that love working out ahead of time why each scene and each line is in the movie loved it. And it gracefully shifted through a whole range of emotions. Good solid movie.
I think that there is a good movie or trilogy with these characters in this setting and with at least one of the many ultimately abandoned themes held in focus, but to get there probably involves redoing 50% or more of the movies to get there.
I'm not going to pay to see RoS so I didn't really suggest how to fix it. But I like the idea earlier someone introduced of tying up a plot hole in the prequels of making Rey the force incarnating itself to try to understand humanity (and thus Luke and Leia's grandfather), just because it deepens the prequels and ties back to them, while adding something original to the ending and neatly explaining the Dark Side vision of Rey being self incarnating.
