The one thing the Doctor always keeps near is the Tardis. So losing it in a black hole somewhere in deep space is a bit of a worry. Not least, he says, because without it he'll have to settle down and get a mortgage. In this two-parter (The Impossible Planet and next week's The Satan Pit), the Doctor and Rose land in a ramshackle spaceship stationed on an obscure planet that's trapped in permanent orbit round an all-consuming black hole. But that's only half the problem. An army of hideous-looking Oods stalks the corridors, while a disembodied voice repeats, "The beast is awakening." Written by Jane Rackham

When Ida estimates the ancient trap door is 30 feet in diameter, the Doctor is standing next to it. Assuming that he's about 6 feet tall, a closer estimate of the door's diameter would be 15-18 feet. See more »

The Doctor: I don't know what's wrong with her. She's sort of queasy. Indigestion, like she didn't want to land.
Rose: [straight-faced] Oh, if you think there's gonna be trouble, we could always go back inside, and go somewhere else...
[Rose cracks up, and they laugh outrageously]

A fantastic revision of the laws of the universe
6 February 2017 | by Maladjusted_1See all my reviews

This is one of David Tennant's strongest episodes yet, second only to "The Girl in the Fireplace" in my opinion. I'd certainly argue that this is the most imaginative episode of the second season.

The visuals are excellent, and the enigmatic Ood are a product of considerable creativity. The host of human characters encountered by The Doctor and Rose are also well-written, although not as memorable as their squidlike cohabitants.

Until now, the revived "Doctor Who" has played things relatively safely. The Slitheen, Sycorax and last episode's Wire are fun to behold, but don't really challenge the logic of the Time Lord's universe. "The Impossible Planet", on the other hand, does. I've chosen not to elaborate here for fear of spoiling the most intriguing plot developments, but I can say with certainty that this episode is one to remember.
