I would have liked to have seen the main characters of the original trilogy not lead such miserable lives after Return of the Jedi. I wrote a whole long thing here, then realized it wasn’t much better than what Disney did and backspaced it.
Maybe we just didn’t need more movies in the Skywalker Saga. But no matter what I did, there would have been a plan. You can deviate from the plan a bit if you want, but there needs to be one. You can’t go from movie to movie not knowing what’s coming next or you wind up with Episode IX. That was how they really failed.
