Doctor Who: The Stolen Earth and Journey’s End – Are two of the greatest episodes of television I have ever seen. Its an amazing collection of talent and action ever in science fiction television. They also bring along Torchwood for the ride. The two episode arc that showcases David Tennant’s greatness as The Doctor. We also see Elisabeth Sladen in a great performance as Sarah Jane Smith. And Penelope Wilton who would go on to Downton Abbey is former PM Harriet Jones is in the mix too.
