Let me just say the score for this story is excellent. Story-wise, this a strong follow up to The Impossible Planet. With Ten and Ida trapped on the planet’s surface and Rose stuck in the base with the rest of the crew, we see the best of their dynamics. I liked the discussion of faith with Ida, I thought it was an interesting element. With Rose separated from the Doctor, we get to see her step up into a leadership role which is just a pleasure to see. The Ood are reasonably menacing as secondary monsters and The Beast is a really solid CGI monster for its time.
