This is, by far, the worst episode of the new 2005 series. The writing is ATROCIOUS, although it apparently appeals to the Brits, as most people rate this far higher than it every should have been. I find it amazing that the residents of a country with such a rich history of art and culture think THIS episode is worthy of a 9!
The writer should be fired and never allow to work on the series again. Let's get Matt Jones in for another 2 parter. the Impossible Planet / Satan Pit episodes were VERY enjoyable.
