The Keeper of Traken - Review

•  Aired in 1981
•  1st Appearance of Nyssa
•  1st Appearance of Anthony Ainley as the Master

The Keeper of Traken is a pretty solid Dr Who episode. The Master returns since the Deadly Assassin episode and we get to see the great Anthony Ainley start his run as the Master.  What's nice about this episode is that Anthony plays most of the episode as Tremas, an actual good guy instead of the evil Master. 
This is Tom Baker's 2nd to last episode and I feel that his performance is not his best. I think that his performance has a lot  to do to the fact that he has no one to banter with. The chemistry between Adric and the Doctor is just not there without Romania there.
The thing that jumps out to me during this episode is the amount of times that the leader of the guards gets knocked unconscious until he's finally killed. The Doctor actually gets him to fall for the huddle trick, where he bangs all of the heads of the guards together while they are huddled up. 
Overall, I give this episode a 3 out of 5 Tardis's. The length of the episode is just right and it's a pretty solid story.
