it's a few things
1. Network bullshit, attempts to maximize profit by pushing cheaply produced, merchandisable cartoons over decent ones, fucking the scheduling for other cartoons. Cartoon network is very guilty of this, the "bomb" schedules they have force the writers to form their plot around the fact maybe five episodes will be released at once every few months, forcing them to fuck with the pacing to keep the shows audience invested
2. Over reliance on cal arts. Nothing in of itself is wrong with the institution, but with such an overwhelming presence of cal arts graduates graduates in the industry, it ends up becoming extremely clique-y
3. Too much storyboard driven content. Storyboard written shows aren't nessiserily a bad thing, again, but the storyborders need to know how the fuck to write a decent plot with good dialogue and pacing, and way too many don't know how to do that
4. Hamhanded attempts at being 'progressive', stemming from writers trying to be progressive simply for the sake of being progressive, make it feel clumsy and unnatural
So how do we fix it?
Fuck if I know, lmao
