To create a situation where each new episode has to start in the exact same place as the previous one, with the actors' hair in the exact same place, seemed crazy.
The idea that you could stitch together every detail episode to episode and preserve continuity for the length of a season and tell a story while using no time cuts, no flashbacks, nothing but pure real time just seemed too difficult.
What you have to get used to as a writer is realizing that most of what you come up with is wrong for the show.
I personally have more faith than the average writer in people's willingness to be complicated, and so I'm thrilled by what's happened. I'm elated at audiences' willingness to handle complexity. In some sense, I feel like my belief in what people are capable of is being validated.
I think ultimately what makes the show is not the reality but the drama.
The beauty behind killing someone who no one thinks you're willing to kill is, of course, that you throw people out of their comfort zone. And that's good because you want people to be on the edge of their seats.
What happens is that as the scripts are rewritten and re-edited in order to make the story more compelling, you sometimes end up with what you could call a time singularity - where there's no way for everything that happens to happen in real time. It's something that you need to wink at.
To be fair to ourselves, in almost every original script, the timing is actually worked out down to the minute.
My background is in math and science, and I thrive on complexity, and I think lots of people do. People love puzzles; it's human nature to want to solve puzzles.
You know, it's hard as a writer to lose characters (and actors) you like. You really don't want them to die because you're not going to get to see them anymore.
The rule, I think, is: Do your homework, learn what there is to learn about the real world, and then when you get in the room, forget it all.
Ultimately people don't watch shows because of how realistic they are. They watch them because of the same dramatic elements that have always made stories interesting. And fundamentally if those elements don't work, no amount of reality is going to be enough to keep people watching a show.
I actually started in the opposite place. I come from a technical background - I'm a mathematician and a programmer by trade - and I was one of those people who would watch a show and say, "Oh, that could never happen."
As far as how important the real-life resonance of the stories is, I think it must play at least a small role in the show's success, because it gives the show this sense of suspense from the fact that it seems at least plausible.
