Nail on the head with the creative stuff. In the early years of Disney SW it certainly seemed she was the one making those creative decisions, with little input from those she should've been receiving input from (i.e. Favreau, Filoni). It definitely shows in the ST. The terrible reception of those movies and the bombing at the box-office of Solo (a movie I've often championed) seemed to change things. Then Disney+ came along and we all know the rest. Maybe she realised at that stage it was right to take a step back from the creative side. Or other powerful figures at Disney realised it and forced her hand. However, the upcoming movies certainly have a feel of ''Kathy in full creative control'' about them.
There's no doubt above her credentials outside of Star Wars however, as both a producer and executive producer: Gremlins, Back to the Future, The Goonies, E.T., Jurassic Park, Schindler's List, The Sixth Sense, Munich etc. I can see why George handed the reins to her.
I've never liked her political agenda. Star Wars is as much a place for inclusivity and diversity as anywhere, but it's done incredibly clumsily at times (see the High Republic as a perfect example). It borders on being offensive to those it's trying to champion (e.g. the a-sexual guy and his rock in the HR). Then again Disney is such an overtly woke company that whatever they put out, be it Star Wars, Marvel, Pixar etc., will always be agenda-driven. I doubt even if you put Favreau in charge of Star Wars much would change in that regard.
