A very hot take: there is absolutely no reason to complain about adaptations of Tolkien works adding more women and people of color in prominent roles.
"BuT iT's NoT cAnOn" do you have any idea how many things were changed in the LOTR Trilogy? A lot. And you won't let that damage your love for it. You're so obviously biased that it's not even funny anymore.
Hey, guess what? Legolas is supposed to have dark hair, not blonde. But you'd have a difficult time making that into reasonable critique.
Tolkien isn't perfect. He made very good but flawed books. His female characters aren't the greatest. People who adapt his works can fix that. Acknowledging that isn't going to open a rift that destroys time and space.
You're just racist and misogynistic. Please shut up and leave us in peace.
