Rey’s marksmanship is a perfect example of the sexist bullshit that is the Mary Sue argument. Think how common it is in movies (not just Star Wars) that a guy picks up a gun for the first time and his aim and ability is never questioned. Yet they go out of their way to show that Rey isn’t perfect with a blaster but people call it out anyway.
Name some examples. I want examples where it is established that the character has never fired a gun before, and takes place in a story where a similar established character misses a lot, even though it shows that he already owns a gun.
Ellen Ripley isn’t an example.
Because you didn’t point out a scene which established that Ripley had never fired a gun prior to the first time we see her fire one, for starters.
