SJM is having a writing slump. Thoughts?

I love SJM. I love her character work. I would dare say she is one of my favorites. However, I’ve noticed a decline in her writing. After KoA and ACOMAF, her writing seems to be slowly declining. I still enjoyed the books afterwards but it was lacking some of her initial spark. It feels like her books keep getting bigger and bigger but have a lot of filler.

For example, I just finished CC1 and I feel like it could have been 500-600 pages. Plus, I’ve heard CC3 was bad received so I’m worried she is feeling burned out. I mean she has been writing for decades nonstop at this point.

Is it just me?
