So Gallifrey has been invaded by these aliens called Vardans, and the Doctor’s been playing along because they’re telepathic and can detect treachery. They spend part three and the first half of part four not fully materialized, in sort of a shimmering thought-form. This is an incredibly interesting idea that looks incredibly silly, because the BBC just couldn’t make this concept work very well. When these powerful enemies finally do show themselves, it’s just three actors in basic sci-fi military uniforms. Amazingly, the show even underlines the flat revelation by having Tom Baker and Milton Johns complain about how disappointing it is. A comedy womp-womp sound wouldn’t have done worse.
Some of the actors in this story are very good, especially Baker, Johns, and John Arnatt. Unfortunately, the Doctor spends most of part four in the company of the Chief O’Hara character that I mentioned last time, a guy called Andred who’s there for the Doctor to explain all the plot to. I’m sure the actor’s a very nice fellow, but this character is incredibly annoying, even more so because I know how this story is going to end next time, and forty years hasn’t made it any less stupid.
