I don't have an explanation, but it seems mainstream media has chased off every decent writer, and I can't imagine how they did it.
The Writer's Guild of America strike of 2007 was the beginning of the end. Remember that shows that were still airing at the time were either canceled prematurely as a result, or if they stayed on the air and continued afterwards, the quality notably dropped. The talented writers never returned to the industry. Cheap, newbie writers did, and they never got better.
Also this:
but my general observation that the writing in modern TV/Video/Cinema doesn't rise to the level of decent fanfic stands.
We live in an age of the fanboy where the average adult in the entertainment business has at some point or another actually written fan fiction. It's a double-edged sword, and the woke mindset isn't helping. I will still swear until my face turns blue that the Legendary Monsterverse has been some of the best fanboy movies to have come out in modern day, because the people who worked on those movies actually love monster movies, especially
tokusatsu/Godzilla, and they knew how to portray Godzilla and gang in a way that was still familiar while adding new ideas and lore unique to that universe.
I get Raye's enthusiasm from a few years back, I get that she at one point actually
loved magical girl anime, but she let her ideas get poisoned by outside influences. She let her ideas stagnate instead of polishing things up. She let her influences dictate its look instead of just using them as a foundation to build something new upon. She
sorta has her own style, but it's still not enough of a disguise, especially since she left behind a paper trail (which isn't usually a bad thing to do in case you get claims of plagiarism) that proves Rosemary was created as an "OC donut steal" of Madoka who uses a sword like Hikaru. Yet the only thing she changed about Rosemary's design over the years was she dropped the ribbons in her hair because it was too goddamn obvious, and her selfies that show she once had pink hair around that time she made Rosemary
doesn't help her case.
Now whose idea was it to have hired Kate Leth to have been a main writer for the series? Most of the problems with the writing were a combination of Raye and Kate's, but you just know for sure most of the issues came from Kate. Did the two write the scripts together, or did they barely interact the entire time? The fact Raye doesn't bring up the people who were "heart and soul" of the series outside of herself while she cries blood over it makes me think she didn't actually make friends with or has any respect for the production team.
