Superheroines and Hollywood

I was looking into information about superheroine movies, and I came across the article "The Time is Right for the (Right) Female Superhero." In the article, the author discusses how the reason female superhero movies in the past haven't been successful was because they were bad movies, not because the lead was a female superhero. I think that makes sense. People aren't going to be opposed to a movie just because the lead is a woman, but if they hear the movie is horrible, they are not going to go see it. When this article was written in 2010, 24 superhero movies had been in theaters in the last five years. I don't understand why Hollywood is so against the idea of putting female superhero movies in theaters. All they need to do is find a strong actress, a good scriptwriter, and a good director, and that would fix the problems they have had with past superheroine movies.
