It's pretty much Girl Boss the movie. Every female character is the best and baddest. The choreography is just dumb. You have battalion level strength with air cover, and armor and you lose to people charging with axes and laser muskets?? Yes the villagers have guns that look like muskets and fire one pew pew at a time.
The zombies in Dawn of the Dead were a bigger threat than a space faring war machine that has been at war for centuries?
They suck at writing so they have to do that. Otherwise, you have to have the Act 2 "beatdown" scene where the main character takes their licks, and learns to become the badass that everyone needs in Act 3.
No one wants to watch a woman literally get beat half to death. It's really rough and it's hard to pull off. Even Quentin Tarantino couldn't really pull it off in Kill Bill, he had to make it exceptionally cartoonish to make it palettable.
Fargo Season 3 probably did the best at this. They literally just beat the shit out of a female character and leave her for dead in a parking lot. It's a brutal fucking scene just for the sound of it. It really sets her up to be a convincing half a badass with a giant male partner in the rest of the season.
Otherwise you have to go like Kingsman and just make an insane female villain with a secret weapon and you have to let her use it a lot during the movie so no one feels bad when she gets half beaten up and killed with the hero's secret weapon in the end.
Anyways...
Yeah they couldn't even follow that pattern with the Mulan disaster. An adaptation of a cartoon that was already a feminist wet dream but at least written competently. Mulan became just another boring Mary Sue and they basically had to rewrite the entire lore to avoid her looking inferior to men
