We've all heard of the Bechdel test. I know it's not a cure-all to sexism and hidden patriarchy, but it is a good question to ask as a writer.
For those who don't know, the original "Bechdel test" posited that 99% of movies don't have two female characters talking to each other about something other than a male. Basically that women in fiction usually exists just to further the plot of male characters.
My novel is first person PoV of a middle school boy and he's part of a trio with two other teenage girls (these are the main 3 characters). But because he is the only PoV, it can never pass "the Bechdel test." Otherwise, I think I've made the other two main characters fairly fleshed out characters.
Don't worry about it.
Look at The Thing, for instance. It instantly fails the Bechdel test by having a 100% male cast, but it's still a story that criticizes toxic masculinity.
I believe Carpenter had an all-male cast because he didn't want any of the characters to be posturing for someone - they are all scared shitless.
Yeah Dr. Strangelove as well is just like that.
