The quoted "competing exec" is 100% wrong when he says Netflix is making a mistake ending shows after three seasons. Shows need to be pitched and run for three seasons max, period. Everyone has a life other than the show that's "hot" for the moment, from cast to writers to the source of money - the viewers. Shows that get dragged out inevitably suck. And yeah, go to weekly releases.
That would be fine if the storylines were wrapped up at the end of season three but shows not only fail to do this, they often end on a cliffhanger and then the series gets cancelled. I don't know about other people, but I wait until a show has been on for years before bothering with checking them out. There are a few that I knew were continued as graphic novels, which I thought was a decent compromise but if I know…
with this as the case, they’ll likely be wrapped at the end of S03.
There’s not much to be done if they’re cancelled before S03.
