'We don't get aliens in Sheffield.' In a South Yorkshire city, Ryan Sinclair, Yasmin Khan, and Graham O'Brien are about to have their lives changed for ever, as a mysterious woman, unable to remember her own name, falls from the night sky. Can they believe a word she says? And can she help solve the strange events taking place across the city?
New Doctor, new companions, new writer, new timeslot, new theme music, and easily the darkest episode of Doctor Who we've had for a long time.
I think overall I enjoyed it. Whilst the episode had its issues, it was a welcome change to the silliness of the past few series. I'd even go as far as to say it reminded me (in a good way) of the initial RTD era, in tone, characters, and even the story.
