2. The End Of Time
The fact I love Timothy Dalton is not the reason this episode is so high on the list. The final ever episode to feature David Tennant as the Doctor is the perfect end to his tenure in the TARDIS. The return of the Master, which although not as menacing as before, is still very well played and excellently written into the shows' lore. But the best aspect of this episode is the emotion experienced during its final few minutes. After fighting off the threat of the returning Time Lords, led by the cruel tyrant Rassilon, the Doctor is left alone, due to the death of the Master and his race, and with regeneration impending, it left a substantial impact on mine and others minds. Some complain that it's too far-fetched - isn't that what Doctor Who is about? David Tennant is at his best, running, laughing, crying, shouting with rage, letting every feeling loose on those around him as the Ood's doomsday prophecies almost come true. Nobody expected the return of the Time Lords, and yet the cleverly-worked out return of the race explains a lot about the history of the Master, and the possible reasons behind the Doctor's pent-up anger and guilt which have been stirring since the shows' return. A fitting send off for David Tennant, the best Christmas special of the revived era, and one of the best episodes, in my opinion, of all time. So why is it not No.1?
