I think I know how to get more females to these types of movies... What we do is have Black Widow have flashbacks of her youth showing her making friends with this other girl, they kind of grow up together but then go their separate ways.. her friend later ends up having a kid and invites Black Widow to her beach house, where she tells Black Widow that she's dying and that she needs her to raise her kid. And then at the end Black Widow breaks out in song, something about wings and wind..
