This is definitely the weakest story of Season 19. There’s some great continuity and character development with the TARDIS crew trying to deal with the loss of Adric, but for the most part the story just feels like it was written around Concorde, rather than Concorde supplementing the story.

The script kind of feels like it needed a few more drafts to me. There are a few odd moments that probably wouldn’t have made it to a final screenplay, like the Master’s Kalid disguise serving no purpose within the narrative, and the Doctor just straight up abandoning Tegan at Heathrow at the end of the serial. I mean, seriously: what the hell, Doctor? The least you could have done is said goodbye to her!

I do like the scenes with Tegan and Nyssa though. Janet Fielding and Sarah Sutton have so much chemistry together. You can tell also that Anthony Ainley is having such a great time. He clearly relishes playing the Master. And there is a great story in here waiting to emerge. They just don’t fully realise it here.
