Why hasn't this movie been promoted as an example of movie with female main characters?
A scifi movie with an all-female team as main characters. A good scifi movie... which has been well received by most of the people who, for example, heavily criticized Ghostbusters reboot. This would have been a wonderful chance to promote a movie with an all-female team.
So what's happening?
Well, in Ghostbusters 2016 males were portrayed as psychopaths or clowns. Or militaristic psychopathic clowns. Fortunately, there were some women there so they could save the day.
You take the Star Wars reboot, white males are portrayed as psychopaths or clowns. Or even as psychopathic clowns, as Hux or Kilo Ren.
You take Black Panther, you have two white characters, one is a psychopathic villain, the other one is a clown. What's the odds, isn't it?
So it could seem that females are secondary, blacks are secondary, hispanics are secondary. What matters is bashing males, and bashing whites, and specially bashing white males.
