Without giving too much away, or adding anything to the comments I made on peoples journals I was left slightly disappointed. There were some clever moments, I watched, I laughed, I wanted to know what happens next. But it left me a little empty. The ending was too tidy and I was left with more "wtf?" than "Gosh, that was good".
Roll on Series 2 - though David Tennant seemed a bit "Oooh, Matron" in his single line.
