Because those arrogant fucks haven't yet internalized the message that there is a substantial audience out there for series that feature GOOD WRITING, nuanced characters that develop organically over time, stories that unfold in their own good time without telegraphing and handwaving and spelling it out like the audience is four, played by actors who can ACT, and that cinematography and capable direction make huge differences in how well a show does. They're still wound up in bankability and flavor of the month and syndication rights--they don't have time for all that artsy fartsy crap that nobody cares about anyway, y'know.
