I only saw TFA once, but if I recall, Rey cries out in this over-exaggerated way, Finn runs to try to help her, and then suddenly she goes ape****. It felt like such an obvious statement the film was making early on in their relationship. I'd also argue, simply from a cinematography perspective, Finn was feminized and positioned as Rey's inferior. These are criticisms of traditional masculine filmmaking, and instead of not using those tropes they leveraged them in the exact opposite way.
Edit: I want to be clear, I went into TFA wanting to see a starwars movie, but this rather left leaning feminist came out of it feeling like I watched a bit of a liberal propaganda film.
Edit: I also want to differentiate what I am saying from the "Mary Sue" arguments. I didn't like that about Luke either, but that's a weakness almost every single fantasy story has. I don't mind that she kicks Ren's ass, or can suddenly use the force any more than child-me didn't buy Luke's rise to power. My issue is more with her lack of any real substance and the forced almost hammy "Hey, feminists!" scenes. In a secondary way her personality was just lacking. I didn't like that about Luke though, either. In both cases, I think it's about selling more.
