Even then it's obvious trying to have stronk action women is box office poison as that just alienates the whole audience: men will only care if it's some og tier Charlie Angels type of whores with sex appeal, women will only care if it's the classic young adult roastie protag with a lot of handsome hunks trying to win over her, yet Ballerina like most nu-female centric action movies has none of that
Regardless, realism in action movies is still nonsense, they've always been about one guy vs a small army and dodging bullets like a ninja etc.
