A movie about a bounty hunter as an antihero or the villainous equivalent? Can Disney actually write a compelling script to do something original and risky?
Well, if "Solo" shows Han being deviated from his ANH persona and they show no reason to harden him up (don't tell me "Solo" will get a sequel, "Duo"

, to explain that - the seeds and sprouts need to start in the first movie - "Solo" - or else it's not going to be believed)...
And just what will they do with
Baby Fatt Boba Fett worth doing, anyway? Is he Phasma's biological father? As if anyone cares, Phasma has been poorly written for two movies now. Oh, some great lines of dialogue (she had some compelling moments in TLJ) but then she gets killed only to reappear in the next movie for no reason then gets killed again. Like the Master from "Doctor Who".
But the franchise will wear itself out because it's trying to find stories to flesh out characters
that don't need any expansion to begin with. Not when all they do is dip into ANH and TESB, find a few scenes that introduces characters, then turn those scenes into 2 hour movies, which adds nothing of substance. Without the movies, the events spoken of are supposed to be awe-inducing (or show the events and don't do it right, then everything looks stupid. Thankfully, from what I'd read and seen in reviews so far, the highly vaunted Kessel run does hold up to legend. Thankfully.)
We've seen that with pointless flicks in the form of "Rogue One" and "Solo", the former upending continuity since its events affect ANH that comes almost immediately after.
