Most title crawls post-OT have been fairly unhelpful in setting the stage of their movie, or in some cases are actively confusing and misleading, and usually get rewritten in most fan edits. The Last Jedi’s was probably the best and even that got tweaked in these edits. I hope this movie won’t be need it (besides adding “Episode X”) but I guess we’ll see.
I am curious if this movie will have anything that necessitates going back to undo changes in TROS Ascendant. I doubt it, as nothing in TROS that was cut for Ascendant felt important enough to be referenced 15 years in the future, but still…
Also, just to throw in my 2 cents on the movie: I’m not sure I like the wording in the announcement that made it feel like Rey is just starting her order. Fifteen years feels like a long time to wait to start your new order, especially when you’re the only one. If Rey had a heart attack or slipped getting out of the shower, that’d be the end of the Jedi, haha. They did something similar with Luke in the new canon, having only seemingly teenaged apprentices nearly 25 years after RotJ, and that felt weird too.
That said, I’m all for more stuff with Rey and the New Republic, and a Jedi Order movie that isn’t the Prequels. I hope Finn is a proper Knight by Rey’s side, because again, 15 years would be a bizarrely long time for these characters to make no progress. It’d feel like the original gap between RotS and ANH, where everything at the end of RotS landed exactly where it is at the start of ANH and we’re just to assume the characters were in stasis for two decades.
