There are countless fantastic quotes from The new Doctor in this story. "These lumps of metal - Daleks - I want them broken up or melted down. Up or down, I don't care which - but destroyed!" "It will end the colony's problems, because it will end the colony!" This Doctor is so much fun.

The whole cast is on good form though. Janley is a fantastic character, a villainous calculating woman in this, who cleverly comes across as ordinary on the surface. Lesterson provides a unique and tortured performance. He slowly breaks down throughout the serial until he is utterly useless. The horror of being forced to realise what a monster he has brought to life is a fascinating development.

There is a great shoot out in the final episode, of which I am sure would improve dramatically if I were able to actually witness the visuals. Even without vision it is clear that this story is brilliant, surely near the very top of most fan’s lists for stories they want recovered.
