Apart from the fact that Sally Sparrow was gorgeous, it was a highly intelligent premise and plot with some great lines too.

Keep it up, Russell T, we love you!

Stephen Moffat wrote this story - although his original version had Sally Sparrow as a 12 yr old girl and the DVD script was originally her school Christmas story. So this was a loose adaptation. I thought it was very good, although I'd have missed out the bit at the end where he's supposedly warning us about every statue on earth. That bit damaged the integrity of the episode, in my opinion.

I noticed the police officer had a Jamaican accent in his old age, which he didnt have when he was younger. A bit of slack continuity there.

Better than many other recent episodes, though.
