The Twin Dilemma
In the Twin Dilemma, Colin Baker has the following line: Well, if he really does believe such unimaginable rubbish he must be faced by some unimaginable disaster which has unhinged his mind. The repetition makes it sound like a line from Plan 9 from Outer Space, but speaking of unimaginable disasters, Doctor Who must have been utterly confident at this point to begin a new era with a ranting, bickering, cowering Doctor dressed in that costume. Add to that a slow and barely engaging story, poor production values and music that follows character movements and manages to be as irritating as Colin Baker.
All I can think is that out of overconfidence (or not particularly caring) the producers allowed one of the worst stories ever at a critical time. The show would never be so confident again. Say what you like about the show being put on hiatus, after that every story at least tried to do something, and we never got anything as bad as this again.
For a Doctor to have a bad exit is unfortunate, but for an actor in the main role to have such a brutal first outing is disastrous. In this case, as all fans know, they followed a great exit with a horrible beginning: the Davison Doctor left showing great courage in facing his own death, and admirable loyalty in staying dedicated to Peri throughout the previous story. And Caves of Androzani is brilliant for that by the end, the Doctor is shrugging off literally everything to stay focused like a spotlight on saving his friend. It may have made sense at the time to follow it up with a less dramatic story to provide a break, but the contrast couldnt be stronger given that the new Doctor cowers in the face of, well, nothing more than slow moving slugs.
Highlights of episode three include space lieutenant whats-his-name (who points his gun at the Doctors face every other sentence) getting his feet stuck in slime that hardens like concrete and cutting himself loose while everyone argues, and an ending where the Doctor yells Peri! despite that fact that shes nowhere around, simply because it helps provide an episode climax. In fact, many scenes could be cut, and not just scenes featuring minor characters. In episode one, every scene at the intergalactic police headquarters (or whatever its called) is ultimately pointless. And given that the evolution of the Doctors character here is a misfire (to bring back some of the testiness and confidence of the first Doctor was a great idea, and well timed, but to make the Doctor the most irritating character in the story goes a little too far), some of that overwhelming performance by Colin Baker could easily be trimmed as well.
One of the dialogue highlight from episode four:
Mestor: You really are mad, ha. You dare to threaten me in my own throne room?
Doctor: Did I threaten him? Did you hear me threaten him?
Mestor: Be silent!
Doctor: Watch it, Mestor!
As a villain, the slug Mestor is incapable of a facial expression, thanks to the costume, though he does manage to wave his hands at times. The Doctor says it himself: I dont rate you very highly at all. To top it all off, its more the Doctors old mentor that finally saves the day.
So heres what I propose: a special edition of the Twin Dilemma, where its been edited down to perhaps three episodes, and some of the effects improved. This is a particular set of episodes thats doomed to poison Colin Bakers era as long as any station shows the episodes in order, so since the BBC owns the program they can minimize the damage. A shorter edition of this would be much more tolerable.
