Iger would have just said get me a sequel trilogy on the way. There's no way he wouldn't have allowed time for the setting up of an overarching storyline. He bought Lucasfilm during Avengers phase 1 which was a highly successful set of movies with a central individual running the overarching storyline. There's no reason Iger would have demanded an immediate sequel and not have waited for a complete story to be written.
Hiring Abrams was Kennedy's choice. Hiring Johnson for the second film and giving him a free hand was also Kennedy's choice. Switching directors when you have no pre-determined storyline is about the dumbest move possible and it was 100% Kennedy. That trilogy is an absolute dumpster fire and makes zero sense because Abrams and Johnson played Star Wars tug of war while Kennedy looked weakly on.
Favreau and Filoni aren't infallible. BoBF wasn't great but it's over hated. It had moments and it had to be remembered that it was shot under the strictest Covid rules which made it super difficult to write and film.
But Favreau and Filoni are carrying Star Wars in their backs. Filoni uses Clone Wars to fix the screw ups of Lucas in the prequels and made excellent content. Then Mando was about the only thing capable of uniting Star Wars fans. They're not infallible but they're miles better than Kennedy.
I could point to 500 problems with The Last Jedi and you would simply turn a blind eye to them. That movie was so radically different from the original series that even Mark Hamill made public comments about it. Critics liked it because it was so different from every other Star Wars film. It was so far outside of Star Wars that I legitimately forget it's even part of the franchise.
If you want to see something that was innovative and yet true to the original films, look to Rogue One, not The Last Jedi. Rogue One is one of Kennedy's few wins.
1. Iger almost certainly set a deadline, the sequel trilogy originally had a writer for all 3 films but he said he needed more time and that plan was axed because they announced a film release date before doing any real work on the film. If you don't think that's Disney pulling the strings, I don't really know what to tell you. Disney wanted to recoup the cost of the trilogy, they told JJ to make a movie "for the fans" as a cash grab to get as much money as possible.
2. You're right it was her choice, Abrams was like the 4th or 5th choice and was recommended by Spielberg. Wish he wasn't hired, but whatever, Disney though said to make Ep 7 a cash grab. Disney was the one to push for ditching Lucas's ideas (though some were adapted like how Rian treated Luke in Ep 8)
3. BoBF wasn't hated enough. It's really really bad. I can understand you wanting to defend it because of COVID protocols, but it was terrible. COVID Protocals didn't make them have power ranger biker gangs. Covid Protocals didn't shoehorn meaningless flashbacks. Those were choices made by the production crew that may have been a bit forced by COVID but could have been adapted. Wandavision was shot in a similar timeframe (started before but didn't conclude until I believe November 2020) and didn't have the same issues. It's a bad show. You can handwave some stuff away but it's genuinely bad. It fails as a gangster show, a star wars show, etc. It has some good moments but it feels like bad fanfiction.
4. Of course they've done great stuff, but they've also done eh to bad stuff. It's funny that you blame Kennedy for everything bad, but give her no credit for anything good. Like all the "bad" star wars it's her fault she's clearly the ones pulling the trigger, but the "good" star wars she's not involved at all. When I'm sure she's basically as involved in all the content at about the same level.
5. You could point to a ton of things you feel are wrong, but they're not problems. Mark Hamill has made many comments you wouldn't agree with on his opinion of who Luke is as a character. It's not remotely close to being out of Star Wars. You saying that means you don't really get what Star Wars is about. It's easily the most Star Wars film of any from the Disney era. I'll happily defend my point with references.
6. Rogue One is a great film, as is The Last Jedi, Solo is fine, TFA is meh. TRoS is garbage.
