Each week the machine is spitting out a number for a new person or a new world within New York that you get to know. And the idea from the beginning was that some of the characters would stick around and become part of the lives of the show, and the world of the show itself will continue to grow.
For me, the attraction of TV is that you continue to get to tell those stories and refine those characters. The other thing is that TV, in the last years, got really, really, really good.
Television is very different than working on film. With films, you get to develop a set of characters, and then, at the end of the film, you have to throw them away.
Typically with HBO shows, the ninth episode often winds up being a big one and when lots of exciting stuff happens. And then the tenth one is the more placid, character-based one.
