I, for one, am sick of seeing nothing but male main characters. Particularly when they are scraping the bottom of the barrel to the point of doing an Ant-Man movie, yet don't give an interesting female character any screen time.
At this point, it's almost like they're saying, "Any male character, even a cipher like Ant-Man, is preferable as a focus for our resources than a female character."
That is not an acceptable viewpoint on the part of filmmakers, IMO.
