To be fair, Owl House is mostly episodic except for the first and last episode. There was barely any set-up and things just happen. I guess most creators feel that there needs to be a narrative with a set-up and epic conclusion to make art. eg. The Last Airbender
I think the main reason why so much shit is story driven is because they don't really have room to not focus on the story coz they don't get renewed for shit, so most of the serial episodes get shoved down the backburner as 'excessive'
Keep in mind Adventure Time had like 10 seasons
