Star Wars syndrome. How could they not know that pumping out so much product so fast would hurt the franchise?
Well, I mean, they probably did know that, or at least realize it could happen, but everyone was under pressure to build their own Netflix.
Sucks for the people who are currently making the shows that will probably have to wait a while to be released ("Agatha: House of Harkness" is filming right now, but I've heard the early 2025 guess elsewhere), but hopefully they'll end up making fewer but better shows or at least trying to make MCU shows a real event like WandaVision was.
