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.
I didn’t say that’s why it was failing, just that the lack of an overarching vision for the franchise has made a bit of a mess (as evidenced by the vastly different takes on Star Wars provided by the sequel trilogy, in my opinion) and that they might be better served by emulating the Marvel model. And it wasn’t something I suggested they do with the sequel trilogy; obviously they can’t since it’s already two films in.
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.
After two offshoot films by different writers/directors, one of which flopped, and two saga films by different writers/directors, one of which split the fanbase. And the director who split the fanbase was handed this new trilogy.
Sounds like a winning strategy.
