What really sucks about the way Joss Whedon writes is that he sort of has this idea that if he writes about women being strong and confident, that is all it takes for women to appreciate his work. Like, even if the villain constantly belittles a woman for being a woman and people are constantly harassing her and sexualizing her, it’s okay because she’s strong and she can take it.
The biggest difference between Whedon’s version of Wonder Woman and Jenkins is that in Whedon’s version Wonder Woman is A Woman. She (and the audience) must be constantly aware that she is a Woman, that she is Sexy, that she is overcoming incredible odds because she has the terrible disadvantage of Being Born A Woman.
Whereas in Jenkins’ film Diana simply exists. There are some points made by other characters about her being a woman, like when Steve won’t sleep with her because he feels it’s improper, or when his secretary says, “Oh yes, put specs on her, like after that she won’t be the most beautiful woman you’ve ever seen”, but Diana is almost completely unaware of her status as a Dreaded Woman. Her excitement over a baby? She’s literally never seen one before. Her little makeover seen? Spends the whole thing looking for something comfortable she can fight in. She basically never mentions the difference between men and women, never even says that women are better or whatever because she was raised by them.
Joss Whedon would have never let Wonder Woman forget she was a Woman. She would have constantly been making comments about it, wether positive or negative, as would everyone around her. In Whedon’s heyday that might have flown a lot better, but now women seem to be a little sick of grrrrl power. They just want power. They just want to exist, both on screen and in life, without constant reminders that they are Women and that they must pay for that at every turn.
