"I’m not saying I don’t want to do it, or it shouldn’t exist. I’m just saying, “Boy, every idea that I had went into this season of ‘Watchmen.'” I’m going to put up my antenna, see if it’s receiving anything. If it’s not receiving anything in a reasonable period of time — and I’ll just say off the top of my head, it feels completely and totally arbitrary, but like a couple of months doesn’t feel unreasonable, you know, January, February, maybe March — then I think we move on to your question, which is, if not me, then who?
Because I actually do agree with HBO that this should be a continuing series. Maybe it’ll continue in a year or two, maybe they’ll continue it in four years or whatever, but I want to see more “Watchmen.” I always said to them, I do see “Watchmen” as “Fargo,” as “True Detective.” They were ongoing anthology shows, but each season had a design with a beginning, middle and end that allowed subsequent seasons to feature entirely different characters, or even be set in entirely different time periods. That’s why I think HBO is calling it an ongoing series. I didn’t say to them, “Guys, this is going to be nine episodes, and it’s going to be like ‘Chernobyl,’ and then we should just walk away.” And so it’s unfair for me now to say, I’m changing the rules."
