Point is, the GA doesn't know who she is.
GA didn't know who the Guardians were or numerous others. That the job of the studios to market the movie to get their interest
It's not just about popularity beforehand vs studio marketing. The question is does the concept rock? Is it likely to be popular based on what people like and what's missing in the market?
You guys think the failure of all female-led superhero movies thus far is the reason there hasn't been any other since?
Because most people enjoy seeing males experience the male power fantasy, and few people enjoy seeing women experience the male power fantasy. It's really that simple. This results in the following symptoms, one you alluded to:
1) Critical and commercial failure, even when the studio does it's job and puts great passionate talent on it, giving the impression that a good one can't be made, except possibly by a select few superstar filmmakers.
2) More success for male-led action films with similar budgets and less talented actors/filmmakers, making them a better investment due to market bias.
This gives me an idea.
An entire team of Marvel superheroes comprised of women.
That would be revolutionary considering all that is marketed to little girls are dolls that look like prostitutes and neon ponies.
To be fair, half of them actually are neon ponies.
I think that's the ticket though. I did have an idea not unlike this involving Captain Marvel, Spectrum, Jessica Drew, Patsy Walker and a couple others. Throwing Phyla-Vell and She-Hulk in there would be fun too. A sort of female Avengers thing. At the time I tied all their origins to the Kree along with Carol, but perhaps something slightly different could be done. It's a hard story to tell without being corny because it's so obviously a female Avengers. I would try to break it in though, make it work. I think there's something there.
It's more possible though, that a small studio will make a Lucy or something like that that will be a major superheroine. DC and Marvel know/feel their male superheroes are their cash cows.
