I am absurdly overexcited about the new season of NCIS. But I've realised it fills the same place in my TV watching that chuggington does for my DS - a cast of familiar if stereotyped characters that I'm emotionally attached to, and comfortingly repetitive plot lines. Though I'm assuming that at his age, DS does not feel about Koko et al the way I do about Special Agent Gibbs (yeah, I know he's old, but I am too, so I reckon it's ok to lust).
So, what fills that Chuggington-shaped hole in your life?
