(or about the Spider-Man movies, at least,)
…is that they always have to give Peter Parker a love interest whose only purpose is to make him worry about her getting hurt. Whatever else is going on in the story, Peter Parker needs to angst about whether his being Spider-Man puts his girlfriend at risk.
We had five movies of this now. Five movies of Peter breaking up with his girlfriend because he doesn’t want her to get hurt. Five films of her breaking up with him because he can’t make up his mind one way or the other. Five films where villains realise he cares for her and target her specifically, so that Peter has to rescue her. Even when it’s as strong a character as Gwen Stacy in the newer films – who is smarter than Peter, accomplished, independent – she falls into the same role.
Occasionally – such as in the latest film, The Amazing Spider-Man 2 – the writing acknowledges Peter’s protectiveness as a problem. Gwen Stacy is intelligent, capable, and independent – and she has specific knowledge that will help with what Peter’s about to do – and when Peter tries to leave her behind to keep her safe, she calls him out on it. But even then, the narrative inevitably goes on to prove Peter right.
These characters, even when they aren’t actually fridged, exist to present the threat of fridging. Their place in the story is to be the potential woman-in-refrigerator, so that Peter Parker can agonise over the danger he is putting them in.
Now maybe it’s true that these issues are just inherited from the comic books, that the creators are adapting the stories that already exist. But by doing that, they must acknowledge that they are perpetuating this trope, the image of the love interest as a victim, or potential victim. After five movies of the same thing, it really starts to stand out. It’s time they tried to do something different.
