There is nothing that says females can't be superheroes. A good movie is a good movie. A lot of times, they make bad movies.
Captain Marvel as a superhero movie is perfect.
Parts of the first Wonder Woman works as a superhero movie as well as her scenes in Zack Snyder's justice league.
I can't speak on The Marvels because I don't see movies In the theatres, I know the villian is powerful.
1984 was ruined because of WB politics and an anti Snyder agenda, sane thing happened with Shazam 2.
Black Widow was only made because Disney had to justify giving Scar jo more than 20 million dollars for being the cool girl at the nerd table and had to justify it. It was a half hearted effort that failed in translation.
Birds of Prey was some shyt somebody came up with to keep Margot Robbie happy while they were still figuring things out with the Batman franchise, it mostly doesn't work.
A lot of comic book material gas been mistranslated and often time, overused, like the Dark Phoenix storyline. Some stuff should have never been used in the first place.
We cannot say definitely whether or not a women can be a superhero until a trailer cones out.
