Day of the Daleks
The Curse of Peladon
The Sea Devils
The Time Monster
The Three Doctors (first episode)
1973 Doctor Who Annual (3)
The first Who from 1972 that I encountered: I am not completely certain if I saw any of the episodes at the time; this was the year I turned 5. The Three Doctors, whose first episode was shown on 30 December, was repeated in 1981 as part of the Five Faces of Doctor Who season. I was 14 then.
My favourite Who from 1972: I really like The Curse of Peladon, an attempt to get political that rather bravely misfires.
Moving swiftly on from: The Mutants, where the best bit is the scenery of the location filming, and the second best bit is Geoffrey Palmer (killed in the first episode)
So, what was your favourite of the above? What is the best bit? (And if you like, what is the worst bit?)
