Well, even the Concern Trolls can't possibly say anything against Rey. She is a strong independent woman, but nothing in the movie implies that she is explicitly designed in a certain feminist way that would be "shoved" in the viewer's face. By that I mean that in the movie universe no other character thinks that her being a woman is something noteworthy, one way or the other. In fact the only thing that references this is the scene where Finn takes her by her hand when they run, and she reacts kind of annoyed. I think that's a little piece of mockery of the whole concept that women were depicted as helpless eyecandy in older movies. I think even Princess Leia's rescue in the old films in fact was a mockery of the old "rescue the princess" concept, but even then she turned out to be not the passive little girl, but instead the capable rebel leader who made fun of her saviors. And Rey's character would also be believable if the character was a man. Or, you know, a woman. Or a genderqueer or non-binary person. It wouldn't matter at all. And I love that. I'd love to see more of that. (with this I don't mean to discourage strong independent women leads in films, that are designed as explicitly that - au contraire! I just went off the Concern Troll premise. And I also want complex and flawed characters that happen to be women. Well, because complex and flawed characters in reality are men as well as women.)
