We still have procedurals and they work and often are a lot of fun - but more and more we move from contained episodes to the full flow of "serialized" seasons, the courage of allowing time for characters to fully unfold. As Scott Gimple (executive producer of The Walking Dead) says in below roundtable "A movie is like a date, a TV series is like a marriage." You get involved for the long haul - you don't need to rush things. The Wire, True Detective, Breaking Bad, House of Cards, etc. etc. - things sure have changed and audiences around the world are loving it.
It used to be that television was the place where you learned the craft to then went on to greater things. No more. Crafting the great dramatic series of today is like writing a series of novels. Your audience comes with you, they watch your season as they would read a great book, unable to put it down - they binge on your show. And they can't wait for the next one to come out. These are golden times, indeed. Watch these three excellent showrunner roundtables and I can guarantee you, you'll start looking for the doors into those writers' rooms!
