Does anyone actually want an MCU style 20-film intertwined arc for these films? I much prefer jumping around on the timeline and letting stories live by themselves, and I think that’s a space Star Wars has been much more comfortable occupying. If, in Solo, Han had encountered an Infinity Kyber crystal that was somehow vital to saving the universe in Episode IX, I’m not sure how that would make anything better.
The idea that Star Wars is “failing” simply because the ST doesn’t have an overarching vision is silly for a million reasons, least of which that 90% of trilogies in existence don’t have that, and most of which that the trilogy isn’t even completed yet. As for the suggestion that Kennedy is solely going for a random and scattershot approach, that’s not even remotely true. Literally the only new films currently on the roster are two series of movies, both with the exact thing you mention - an overarching creative director.
