The writing was just… so atrocious in the last trilogy. Like, no coherent themes or through lines, characters were bland and poorly executed, dialog was clunky and stilted, pacing was none existent and the story was disjointed with completely un-engaging stakes.
Like, some say “oh well that’s true of all the previous star wars films” and no, it wasn’t. Some of that was true of some elements of the first and second trilogy. But none were all of that at once.
I just have… no faith they’ll do anything interesting. Once is a fluke, twice is bad luck, three times is a pattern. Disney’s modern methodology for producing films is clearly flawed at some fundamental level. The chance that the corporate machinery has realized there is a problem, correctly identified it, and then actually fixed it is close to zero.
