It was about the force being stronger in certain bloodlines , what was the force for rey? Oh yeah , training isn’t needed even though all the masters were trained . A mary sue isn’t a 9 year olds argument? Anakin was destined to be one of the most powerful , rey was a better pilot than solo , chewbacca , luke and anakin . Skywalker was at least a pod racer and relevant to the Canon. Didnt rey also say she had never flown before? But could pilot the falcon alone? She was stronger than luke , they even pulled teleporting abilities out of their ass to show she was something levels above anything else . She is the definition of Mary sue and its what alot of people didn’t like just like captain marvel .
So the 9 year old thing doesn’t fly man , she also could force manipulate storm troopers without even knowing what it was , then there was the fan fiction love story with kylo . Lukes arc? Yeah they straight up buried his character and dont even get me started on the writing . The prequels were closer to starwars than those three were and because they made money? Doesnt mean the majority liked them.
Its like any marvel movie the name alone sells , captain marvel? Black panther? They sucked but made money
