People who do not fear equality would not have batted an eyelid at That Scene.
Disagree. To "not bat an eye" at the scene would be to not have an emotional reaction to it (either in the affirmative or negative). I thought it was a great scene and as such I responded to it very positively. For one thing, the USA is no longer the primary audience for the studios big tent pole films therefore the image of minority (especially women) empowerment and inclusion is very important (and good business).
Honestly, I do not know how well an all-female lead superhero movie would do (prejudices being what they are), however, I would very much love to see one get made and feel it is imperative that one does. My only fear is the studios have it written as if it were a bunch of men then cast women. To avoid that I would go further and say I would hope it would be written by women as well as directed by one (In addition to Brie Larson, Karen Gillan would also love to direct a MCU film).
