Episode complete credited cast:
Gabriel Woolf ...
The Beast (voice)
The Ood (voice)


The supposedly servile Ood are now in the control of some type of beast that describes itself as Satan and claims to be a being that has existed since before the creation of the known universe. Rose takes charge and tries to find a way to get everyone out safely. The Doctor and Ida have descended 10 miles into the bowels of the planet only to find themselves trapped there and unable to return to the surface. They find evidence of a ancient civilization and a seemingly bottomless pit where the doctor confronts the beast and finds the solution. The only problem is that the solution may kill Rose.

There's no backing down in this incredible follow-up
7 February 2017 | by (United Kingdom) – See all my reviews

As I was hoping, the writer(s) of this episode chose not to back down from the groundbreaking revelations introduced in "The Impossible Planet", and The Doctor comes face to face with something far more menacing than almost any of his previous foes. But neiter he nor the titular antagonist are the star of this episode.

Rose is awarded several of her strongest, most driven moments yet. Cut off from The Doctor, she assumes a leading role in the handling of the Ood threat. When she isn't following along as the companion, Billie Piper is capable of giving some very good performances. You'll find such a performance in "The Satan Pit", which I really think is a Rose episode.

The host of supporting characters, with the exception of the still-eerie Toby, are more entertaining in this episode than in "The Impossible Planet", and the point at which they realised they had to cooperate is rather well-written.

Overall, this stands as one of my favourite episodes to date, rivalled only by the first season's Dalek episodes.
