After Kylie at Christmas, the Doctor met an old friend, Donna Noble and took her off for adventures across space and time. They met Adipose, visited Pompeii, freed the Ood, hit to Sontarans on the back of the neck before Agatha Christie, and finally Davros and the Daleks.
It was quite a series, but which one was your favourite?
