Doctor Who - The Christmas Invasion

While The Doctor regenerates london is under attack from cycorax

The very first Doctor Who Christmas Special with David Tennant as the Tenth Doctor.

Rose and The Doctor crash land the Tardis in London on Christmas eve. The Doctor is starting to feel the sideffects of the regeneration and it is up to Rose find a way to save him, as well as deal with her own grief and confusion of losing him not just once but twice.

To make matters worst and Alien army known as the Cycorax, break through Earth's atmosphere and threaten to inslave humanity.

Reflections:
In this episode we see Tennant try to assest himself as The Doctor, he still holds that little charming quality the Doctor has always had, but now he surfaces a darker side of himself. In a memorable scene between the Doctor and the leader of the Cycorax the Doctor asked himself what kind of man he is now. And the Cycorax leader, as well as everybody else got to know this Doctor offers no second chances.
