Unlike most British series, which have few episodes and a single writer, each episode of the Doctor Who has a different writer, with Moffat writing key episodes and overseeing the story lines. This can lead to very different tones, from humorous to chilling. “Gareth Roberts, one of my fellow writers on Doctor Who, had a theory that you write the Doctor Who you remember.” Moffat explains. “He tended to remember the funny ones, so he writes funny Doctor Who, and I remember just being terrified over it, so I tend to write the scary Doctor Who. Neither memory is more accurate, it’s all kind of nonsense, but I do like the sort of weird sense of transgression of it being slightly wrong to have a television show whose mission statement is to petrify kids.
