First, those were not negligible mistakes, they had enormous consequences, and both stemmed from one of her character flaws. They're there, which undercuts the assertion that she had none.
Also, she hits two before fleeing: one she got the jump on and still missed, and another who wasn't aware she was there and was not far away, she blind sides him. She later hits another from cover who is chasing her. Not exactly marksman work.
Perhaps we're leaning on different understandings of flaws but OK. I don't think making mistakes means a character can't be a Mary Sue.
Sues and Stus are defined by an unbalanced approach in writing whereby the positives far outweigh the negatives beyond reason.
Ethan Hunt is a Gary Stu, but he makes mistakes. He gets caught with his pants down every now and then. That doesn't mean he isn't ridiculously skillful.
The point I was making with the second part wasn't that she wasn't a perfect shot - though she wasn't - but rather her overconfidence and impulsiveness got the better of her and had consequences. These are important aspects of her character.
I haven't once gotten the impresison Rey is overconfident or impulsive on any level. To me she seemed to be going with the flow most of the time and just doing what she could and was capable because she was independent and levelheaded as a result of living a rough life.
Covered ad nausium in this thread and others, but at this point I think it's clear we should move on.
Fair enough. Precedent and pre-established lore are on my side so I don't think this would need much covering anyhow.
Much of the point of the scene early in Jakku is to demonstrate Rey is a skilled melee fighter with her main defensive weapon, a staff, and she used the same style of fighting with the sword later. It's right there in the film as direct foreshadowing of her fighting skills. If that scene were not there, then I think this is a reasonable issue to have, but it was there...
People keep saying this, and to an extent it's true, but this "skilled melee" fighter is somewhat of a mischaracterisation of her skills.
Rey can scrap. She is tough as nails. But she isn't a martial artist or anything. She fights two random thugs at the beginning and gets hit a bunch of times but prevails because she's tougher than they are and she's got a stick she knows how to use.
That does not - and should not - somehow display transferable skill to other weapons. Certainly not lightsabers, and certainly not in the context of a fight with a character that is trained and experienced and has all this fanciful choreography and lethality to them that makes their expertise so self-evident and clear.
I've said it in the main spoiler thread: though I wouldn't write it myself, Rey winning that fight is not the problem. It's the way she won it.
Ren was injured, but he didn't lose because of his injuries. He was winning in spite of them.
If Rey had won by scrapping it out, by being tough and clever, and perhaps even fighting dirty to reflect her survivor background and determination to stay alive - then we would have a great fight with a satisfying ending. Or at least that's my opinion.
