Missy aka Gomez was/is one of the best villains we have had in a long time, a right old nutter. She is brilliant at that, laughed much at her character in Green Wing. I hope the writers find a way to bring her back. PC is a good as a doctor, but need a much better side kick and better story lines. The last two doctors first season had episodes I wanted to re-watch right away, this season is lacking, but I will probably watch them again at a later stage.
I wonder how Nick Frost will do as Mister HoHoHo.
