I didn't name Kennedy because it's too easy to dump all the blame on her. There are a host of people at Lucasfilm that went along with this. I'm sure there's at least one other person at Disney/Lucasfilm who backed her play. Probably many.
I despise how Kennedy has run the franchise into the ground, but I also despise the people who helped it happen.
For sure Bob Iger approved her management, at least initially. "The Force Awakens" was terribly derivative, but enjoyable as a "sugar rush". "Rogue One" went through a lot of trouble but the end result was fine. Everything collapsed with "The Last Jedi" (as I said elsewhere, when I first watched it I came out of the theatre wondering if they had distributed the wrong version...) However TLJ was deliriously "embraced" by SJWs and Disney found itself in a quagmire: how they could fire the "story group" that had run the franchise to the ground, after their movie was being exalted by "The Custodians of Pop Culture" (*) and, even worse, while with a woman at the head?
I never liked J.J. Abrams as a content creator (in person he seems a nice guy). To me he is a hack of the worst kind (sadly, I meet many in my career in comic books; and yes, almost all of them went farther than me...

) However, helming "The Rise of Skywalker" would have been a desperate task for everyone. It is known that Abrams got a list of things that
had to be in the movie, and if you look closely TRoS takes TLJ, scene by scene, and does the exact opposite. IMHO, only Bob Iger could have ordered something so radical, but letting thing go out of control the way they did was a serious dereliction of duty. And then the curtain fell on the whole mess.
(*) Since our good friend Ghostmaker wasn't able to post an example of "leftist foolishness" in another thread, I'll do it for him here. Fiery defence for TLJ values produced pearls like this one:
https://www.esquire.com/entertainment/movies/a25560063/how-fans-ruined-star-wars-the-last-jedi-2018/"...These trolls launched an entire campaign to finance their own fan-made Star Wars film. While this is a laughable idea for delusional racists [because if you want to finance an independent Star Wars film you are a delusional racist: one thing logically follows the other], the message was clear. As the campaign’s manifesto read, "The fans are completely divided [we know: YOU wrote earlier "45 percent from fans on Rotten Tomatoes"] and the core goal of Star Wars has been abandoned. The goal is to not make one half of the fandom happy over the other, it is to make a film that the fandom in general as a whole enjoys." [the point, here, being condemning this statement for its absolute banality, I guess] [...] It’s fucking insanity. And let me just take a moment right here to remind you that this is a family movie, largely designed to sell toys to children [which, as it happened, is exactly what it failed to do, so maybe the "trolls" had a point.]This was, of course, 2018. In the modern age, the way "Star Wars" was mismanaged is the object of studies. Maybe Rustin Cole is right: the light is winning.
