Could one issue be that professional writers, on average, give female leads worse scripts to work with? Not always intentionally.

I feel like this is a pattern in Star Wars. Not just with Rey, but Ahsoka and The Acolyte too.
As for why this is a tragedy, I would cite the A/B examples of AC: Odyssey and Cyberpunk 2077 where, given the literally identical gender neutral writing, the women VAs utterly nail their scripts.
I wonder what’d happen if TV got the same treatment.
