Why does this happen? I suppose it’s silly to ask. (Heterosexual) Men want women’s crotches in their faces, even if they’re being beaten up. Still: ridiculous.
Or is it because female sexuality is threatening? Our weapons are vaginas!
Unfortunately, what I think it is is that male-female interaction on screen is almost required to be sexually charged. It’s pretty sad that they slip this so effortlessly into violent situations.
