Did You Know?


Russell T. Davies originally wanted Helen Mirren for the role of Adelaide Brooke. See more »


When the Daleks invaded Earth in the episode The Stolen Earth, they were intent on destroying all of reality, except for themselves. It therefore makes no logical sense that they would just leave the young Adelaide alone instead of exterminating her or taking her aboard the Dalek crucible. See more »

Highly unbalanced
30 November 2009 | by (Romania) – See all my reviews

It was like an average Doctor Who episode, if you ask me, but it was so uneven that it oscillated between very good and very bad moments, probably because this special has a double purpose: one is to tell a story and remind Dr.Who fans that the show still goes on, the other is to prepare for the coming of the new doctor.

What will probably upset most fans is that in this special The Doctor is changing personality, going more towards "the dark side". I find this development marvelous and intriguing, giving new life to the otherwise pretty used up idea of a perpetually good and balanced doctor.

Bottom line: scary monsters and super freaks, but not very believable. A design of a Moon base that makes no sense. Some useless jokes. A lot of tension and it certainly makes me want to watch the Christmas episode... but it could have been better. The Gadget-Gadget bot really was out of place and, if I think about it, the best part of the entire show was the last 20 minutes.

I tell you this: if Billie Piper doesn't play in the Christmas special, I will be very very disappointed! Her character is what could change the tide, so to speak...
