The Two Doctors
After Revelation of the Daleks, the Two Doctors has to be my favourite DW story at that time and for pretty much the same reasons - lots of continuity references, old monsters and a quite unprecedented level of violence. However, there are many who dislike this story for precisely the same reasons, but I'll just give my viewpoints here.
Firstly, there is the heavy level of mythology in the story. What is wrong with this, in a twenty year old show? A story is only as good as its past and why should such a varied past be ignored? To spare confusion among present day fans? Please! And the humour here is also good, Doctor Who should always have humour somewhere in it and I don't think it was overplayed here. It nicely offset the other controversial aspect of the story, the violence!
This was so cool. I was a growing teenager at this time and DW seemed to be growing up right there with me. Tame stories like the Underworld or the Androids of Tara seemed half a lifetime away - come to think of it, it was. I loved seeing Stike's leg congealed in green blood, or Shockeye stalking a rat; they added wonderful menace and tension to the plot - the violence and the humour seemed to wonderfully dovetail each other out. In the middle of the Second Doctor/Shockeye in the restaurant scene, Oscar is brutally murdered for no good reason by Shockeye. Many people objected to this as too violent, fine. BUT, in a wonderful piece of poetic justice, Shockeye is himself killed by Oscar's cyanide kit, bringing the whole thing full circle. And people objected to Shockeye being killed as well! Okay, it was the Sixth Doctor wielding the cyanide,but he was in a life and death situation and didn't have any other means at his disposal.
The Sontarans were also excellent here - I love old monsters coming back and they hadn't been in a DW story for yonks, and that was the Invasion of Time. Enough said. more than time for their return, which was handled very nicely.
The only slightly peculiar thing about this epic tale is that the two Doctors should meet in the first place - in The Three Doctors and The Five Doctors this crossing their timestreams happened by direct intervention, but here it seems to be more or less by accident. Still, a minor quibble in an otherwise excellent fable. Loved Chessene and Dastari, loved the simplistic plot - but then, I love simplistic plots!
