It shows she has no clue what she is doing. When they went into making Solo, She should have been aware of what she was commiting too, and what it might mean to the fans. Instead she acts like this was a huge revelation to her. She isn't Kevin Fiege for example who commits and makes things work. She is someone who you would almost believe has no idea what she is doing. Problem with Star Wars is that the evidence over the years suggest that when things that got thrown at the wall they didn't stick on their first throw. Lucas would then make sure it stuck even when fans didn't like it. And alot of these things have become an important part of Star Wars that people can't imagine the franchise without now. So Lucas showed he was a good leader because believed in what he was doing. KK throwing things at the wall and saying ah we made a mistake we won't do that again, shows she is still in a learning phase.
