Maybe i'm just seeing things but it feels like a lot showrunners are abandoning ship more often nowadays? Maybe it's normal and I've just not noticed before, but maybe the publisher intrudes too much now to stick around for too long.
The studios don't let the creatives create, they don't want to commision shows they want to control them, so they have to hire people they can control and whom will be happy to do as they're told and take the job, even though they aren't qualified, like the idots running RoP. So anyone with any talent so skip from job to job where they can have some freedom. Studios are driven almost entirely by money, by politics, by what NF etc want and their algorythmns. Theirs and those buying their shows.
Is this every show and every film? no, of course not but it's a good percentage.
It's a production line of copy paste numbers driven crap, made to run x episodes of a certain length aimed at x demographic to fill x slot on x streaming service, with this message and that message, hitting this plot point and that at certain times. It's trend following, it's safe, and it's designed to take as few risks as possible, like games, like moves, keep recycling the same old IP's, remaking the same old films/games/shows...
It's far from all content but a lot of it, it's just a formula, subscribe, consume, repeat where mediocrity is now a good show.
