The Second Doctor, as played by Patrick Troughton, is without doubt the greatest incarnation of the Time Lord. And this, his final story in the role, certainly does him justice. Episodes 1 - 9 are set during World War I... or are they? Actually, the Doctor and his wonderful companions, Jamie (Frazer Hines) and Zoe (Wendy Padbury) have found themselves in the middle of a war game being played by a race of aliens called the War Lords, watched over by the villanous War Chief who, like the Doctor, is a Time Lord, and seems to me to be the direct precursor to the arrival of the Doctor's archenemy, the Master...
This story serves as a dramatic and poignant anti-war story, led by the concept that the War Lords, out of all the races in the universe, chose Humans to play the games with. We have the most wars to choose from. We have more wars even than the Cybermen or the Daleks?
Episode 10 is extremely saddening, and may well bring tears to your eyes. I won't ruing the circumstances for those of you unaware, but as the scenes of the Doctor bidding farewell forever to his companions are very well done, and you honestly believe the sadness felt between the characters when the time comes.
The extras are, as always, awesome. This story is a must have for any Doctor Who enthusiast, and would even be a great place to start for anyone unfamiliar to the world of the Whovians...
