Doctor: 'Tonight, I'm the Ghost of Christmas Past.'You've got to hand it to Steven Moffat—his first Christmas episode was an absolute blinder. It was exactly how a Christmas episode should be: it was different enough from a regular episode to justify its special status; it had regular companions (even if they were criminally underused); there was a strong Christmas theme; it had great celebrity guests; and there was an emotionally engaging narrative which both warmed and broke our hearts. In short, it was both Christmassy and special.
