Did you like Lord of the Rings?
I am guessing not that much either because there are few female characters.
I think it is best to respect the author and let him write, or tell a story in film.
If you don’t like it. Easy. Don’t read it. Don’t watch it.
I didn’t like Emma.
I didn’t like Barbie.
Those movies were not for me, and where female oriented and that is fine.
No problem!
Freedom is best when it can create and reach their audience.
