New Earth

Twenty three years after The End of the World, the Doctor and Rose are drawn to New Earth by a psychic note, to a hospital run by cat nuns (honestly) where their miracle cures they promote. There's a couple of cast reunions, pussy lumpy lesions and coloured infusions, intimate exchanges without ablutions (several in fact) and an uprising or revolution that's the start of evolution, it's all a bit bemusing - just like chasing a ball of wool. All in a not too dissimilar story to Never Let Me Go (by Kazuo Ishiguro), though a lot more extreme, but with a happy ending, for those who survive at least.
