A great episode showing exactly what happens when the Doctor isnt there to save the world. London is destroyed, America is destroyed and the whole world is on the brink of collapse. This is no great surprise given that were talking about a world where, even with the Doctor alive and doing things, the Daleks still managed to take over the planet in the mid- 22nd century. While some of the incredibly non-subtle political commentary was something I could have done without (I strongly doubt that wed have all the non-English people being put into camps, for example), and while I REALLY could have done without Rose (Billie Piper), I still liked seeing how horribly wrong things could have gone without the Doctor. Plus it was a lovely chance to see Donna (Catherine Tate) have her own episode, and Ive always liked Donna.
