Wonderful to see the Brigadier again for the first time in many years. Re-joining forces with The Doctor feels like a rite of passage for Davison’s Doctor. I don’t think Lethbridge-Stewart is particularly well served in the initial school environment we meet him. His newtered, difficult to pin down role in an unrelatable private school is kind of meh. The unrelenting poshness of it gave me K-9 and Company vibes and I think a different setting could have better served the plot.

Once we get out of there though he drives, in younger and older forms, an interesting runaround for our TARDIS crew, including a new, darker, duplicitous companion. Turlough is an interesting character. Clearly a rotten, compromised person who nearly killed himself and a friend through his own recklessness - then lied about it! He is then given a second chance at life by the Black Guardian and forced into doing his dirty work (trying to kill The Doctor). I look forward to seeing how he develops. His school friend however, who looks about 10 years too old for the role, is a horrific actor. I’m glad we won’t see him again!

I’m surprised they brought the Blavk Guardian back as I only vaguely remembered him from The Armageddon factor, though I appreciate that he had been mentioned other times before and after that story. I think the production team believes him to be a more prominent character than he is.

The story was an entertaining one and improved as it went along, but it was ultimately a rompy runaround which focused on characters - nothing wrong with that!
