So, there’s failure from a certain point of view, but from many others she is unrealistically successful (or lucky) given her lack of experience, and naive nature, and she achieves many of these successes with powers that she just almost instantly recieved from on high, and thus hasn’t really earned.
I agree with this.
But I don’t think it would play well if we saw Rey getting beat up like other action heroes tend to be.
Had Rey been rescued by Poe Dameron in a Hoth-like situation, people would accuse the filmmakers of resorting to the damsel-in-destress trope.
If Snoke had been hurling giant pieces of machinery at Rey’s back and head, she gets beaten and bruised with a black eye (ala Luke at the end of ESB) AND she loses the fight, it looks like a display of violence against women, and accusations of misogyny are made.
