When you look into the Tomb Raider movies, Haywire, Colombiana, and other female oriented heroine based movies, that dispelled whatever "credibility" they've had regarding finance. You're looking at superhero flicks that were trying to find a footing. Steel is what ultimately killed the superhero movie genre as a whole and since then, while there have been some successes, most of them were just horrible flops.
Right now, superhero movies, thanks in part of the likes of Marvel, managed to get the genre back into popular footing. That and the three examples you've mentioned were riding on the coats of other intellectual properties (Superman, Daredevil, and Batman respectively - with the third being a botched effort) riding on the coat tails of their predecessors...all of which were at the end of their popularity (save for Daredevil). The bad writing and direction were just muddled and were clearly just for a buck.
Now that has changed. Granted, there is some truth to what you're saying, but the issue is more to do with what I've stated above and quite frankly, a man shouldn't direct a movie with female protagonists unless they really understand and know what to do to keep them from being generic. Henceforth, if a movie were to be done, someone like Kathryn Bigelow would be perfectly suited in bringing the Wonder Woman franchise into the limelight and rightfully so, given her track record. It'll be a big budget, but you're guaranteed success.
I don't think this will ever happen.
it is a financial issue. The movie people will look at all of the female hero movies and say they have flopped. And there is a lot creditability to their comment
We can make that assessment, but more so how to adapt Wonder Woman into a modern setting. Yes, we can consider all that with in the history of Themyscira and how and why they would be less willing to work with a male counterpart. But overall, it's a matter of shaping the history of the land she was brought up, and less to rely upon what they left from.
The comics were written during WWII, so it would have to revolve around themes of inequality, gender discrimination and such, but not too overtly to where it's being preachy. I think the 2009 animated movie did Wonder Woman justice and it should be a good model to follow to help bring Wonder Woman into the modern setting.
This is where an actor has to do a lot of research to find the essence of a character. Not just reading the comics or watching tv or movies. But studying the history of the subject. For the role of Conan, Arnold Schwarzenegger had to do a lot of research like weapons and fighting, all the way to a barbarian's sex life.
