Having a bunch of guys like you judge an actress based on how much muscle tone she has to have to suit your image of what Wonder Woman should look like is bad for women.
So Gal Gadot is now the "most extreme end of the spectrum away from muscular"?
Did Uma Thurman look silly fighting 88 yakuza with a slight frame in Kill Bill? How could Black Widow possibly fight against mechanical alien enemies that are bigger than her and also armored, she has no bulk at all! A good director can sell any action scene,
petite girl fighting someone stronger-looking than her or not.
The perpetual complaining about Gadot's 'frame' or 'bodytype' is really just a disguise for how Gal Gadot isn't the Wonder Woman you envisioned. It's all excuses to complain about how, physically, she isn't your comic book fantasy. She isn't wearing full armor to fight against Superman, but you're not persistently complaining about how unrealistic that is. Instead, here are a bunch of comics nerds defending a Wonder Woman costume design with a battle skirt and very little armor. "Oh, historical reference!" "Oh, this is her classic look!" "Oh, this bullshit and that bullshit!" And on the side they're complaining about how unrealistic the actress's body is. Right.
