Kathleen Kennedy produced so many classics it's not even funny:
E.T.
Gremlins
The Color Purple
The Goonies
Indiana Jones
Back to the Future
The Money Pit
Who Framed Roger Rabbit
Hook
Schindler's List
Jurassic Park
The Bridges of Madison County
The Sixth Sense
etc.
Her Star Wars movies made a few billion dollars in 4 years and The Mandalorian is all kinds of awesome, clearly she's a hack who stumbled from success to success

Is it really so hard to accept that you not liking a movie doesn't mean the people involved don't know what they're doing?
And Rey's as much of a Mary Sue as Luke was but I don't see many people complaining about Mr. Skywalker destroying the death star after 5 minutes of jedi training and trusting the force.
