It’s really cool a superheroine is getting her own movie. It’s about time! There are characters in other movies, like Black Widow as you mentioned. Scarlett Johansson could more than handle a movie on her own. She’s done it before, so why not with that character? About the Thor gender swap, I actually think it’s pretty neat. I have no idea if it’s been done before with another character, but I think it’s a cool thing to try. But they could also certainly come up with more superhero women, since men dominate the field way too much. And there are some great actresses out there to play them!
