It’s interesting that now Marvel Studios seems to be actively considering a movie based on Scarlett Johannson’s Black Widow (Iron Man 2, Captain America: The Winter Soldier and Civil War, Avengers and Avengers: Age of Ultron) especially when you consider that the character should have had one long before Wonder Woman did.
That being said, there’s a bright side to Marvel Studios’ seeming hesitancy.
Namely movies with women as main characters are judged by a different standard than those featuring men (and that’s not even getting into differences in color, never mind sex) in that if a movie staring a man fails, all that means is that some other man, in some other movie, will pop up next.
While, if a female-led movie craps out, then there’s a very real possibility that Hollywood might not make any more movies featuring women as leads (in that particular genre) for a very long time.
For instance, if I recall the last superhero film featuring a woman prior to 2017’s Wonder Woman was Elektra twelve years ago.
So as much as some of us don’t want to admit it, there’s definitely a double standard, and movies featuring women don’t have the luxury of being half-baked, which is why they shouldn’t be rushed into production.
