He said that although he enjoys writing the show, it can be tiring because he has to write for a character like The Doctor, who has such an extraordinary mind.
âThe Doctor is brilliant fun to write,â? he said. âBut heâs exhausting, because youâre constantly trying to write somebody whoâs got an extraordinary mind, when youâve only got an ordinary one.â?
âI have to do that with Sherlock Holmes as well.â?
Moffat also revealed that the decision to introduce a mid-series break was taken because of the âsagâ experience part way through the last series.
âI want to avoid the mid-season sag,â? he said to Doctor Who magazine. âNot a sag in quality, but a sag in event status. It was particularly noticeable last year. Thereâs nothing I wonât do. No, I kept saying, âWe should have a big even in the middle of the series. We should have something that reall attracts attention, so there isnât that sag.ââ?
