The main question I had before this episode started was how were they going to explain the fact that the Doctor has a daughter but he says he is the last of the Timelord’s? The answer was quite simple really and everything in the story worked out quite well (except for one bit but more of that later), the idea that the two armies can be created by sticking your arm in a machine and that the two armies were created in seven days was well thought out and added to the sadness and scale of the situation. The General played the evil general very well and was a good for someone for the Doctor to vent his frusttation and anger at. The Hath were very well thought out but I would have liked for them to have some form of proper vocal cords.
Of all the cast, it was Georgia Moffat who stole the show. I was a bit unsure of her because I thought that they had only really cast her because her dad is Peter Davison. But pretty soon those fears went away and you could see that even at the beginning there was a bond forming between her and the Doctor. Catherine Tate was the best that I have seen her in this series, she actually helped solve the situation and came up with some funny jokes at the Doctors expense. Freema Agyeman was put in a really difficult position where she had to interact with an alien that couldn’t talk but she was able to work with it.
The story was very good and the moment when Jennie got shot was a truly sad moment and it was surprising to see the Doctor with a gun in his hand and not knowing whether he would shoot or not. The fact that Jennie came back to life and went off in her spaceship shows that there is a good chance she will be making a return to the show in future episodes. Well acted and well directed this is another fine episode from this series.
