Have you seen the feminist reading of Mad Max: Fury Road?
You might find it interesting. YouTube is not loading for me, but it's called "The avenging feminine": https://www.reddit.com/r/GamerGhazi/comments/9jzuci/bringing...
My favorite part is something the essayist points out about the mothers [1] in Fury Road: They help in every fight. They shoot, they reload guns, they operate bolt cutters, they deny guns to enemies, they assist with _any_ light work that the buff action hero and heroine are too busy to do. And if there's nothing to do, they take cover without being asked.
The mothers don't start weak and become strong, the movie isn't about that. In fact I don't think anyone in the movie gains strength. Nux has a heel-face turn, but that's all I remember for character change.
Just because they're _side_ characters doesn't mean they _aren't_ characters. There's no scene (that I recall) where you have to ask, "What are the non-combatants doing right now? Standing and watching?"
And even though they're still physically weak at the end of the movie, their actions still matter. The movie doesn't imply there's anything wrong with weakness. Even if they are like pawns on a chessboard, every pawn still matters. I think that's very empowering.
[1] I think only one of them is pregnant, but they are all escaped slaves, so they're not in shape for direct combat.
