Doctor Who 117, Castrovalva, bridges the Tom Baker and Peter Davison years and is part of a series of connected episodes featuring The Master. Castrovalva makes little sense out of its story arc so you really do have to watch episode 115, The Keeper of Traken, and 116, Logopolis.
When Doctor Who ‘s regeneration encounters some difficulties, the Doctor must go to the Zero Room for a while. The Master has rigged a trap for the Doctor through Adric so Tegan and Nyssa must somehow learn to fly the Tardis. They land on Castrovalva, a world the Master controls. Meanwhile, Adric is prisoner of the Master.
The Doctor is well received but not everybody, especially the head librarian of Castrovalva, is a friend. A neat feature to this world is it is very Escher like for reasons that would spoil the plot.
It is no secret the special effects for BBC’s Doctor Who serial make the original Star Trek’s look like million dollar productions. Here, the natives wear ratty fur coats and feathers and Castrovalva is obviously a set.
This is not a great Doctor Who episode. Only fans of this science fiction series will appreciate it.
