KK is a high-quality producer, the biggest knock on her Star Wars is that there wasn't a plan, so results have simply varied by whoever was director/writer. JJ was typical JJ and his movies were dependent on the writing, first was acceptable, but Kasden simply re-wrote what he was familiar with, and his 2nd sucked because Terrio is a terrible writer. Rian did something that was divisive, you either loved it or hated it, and his vision didn't match JJ's or Trevorrow's. The other films were an obvious mess behind the scenes and had varying results on the screen.
When KK had the right people in charge of certain works, it was a huge success. Mainly Filoni and Favreau. KK should get credit for putting them in a spot to do their thing.
The problem with KK is not really knowing what to do with Star Wars and what vision to maintain, and that's why results have been inconsistent.
