And here we are finally, Tom Baker’s last story. It has been a long road since Robot - the longest road I suspect I'll ever spend with a Doctor. Whilst this season has, on balance, been his worst, I can’t say it wasn’t sad to say goodbye. Though we do now have a wonderful cast of new companions to distract us!

Whilst Bidmead is a lousy script editor, his style and tone suddenly makes a lot more sense with his own script. The first couple of episodes are pretty tightly woven with an interesting central idea of The Master’s TARDIS inside The Doctor’s TARDIS, creating a loop.

It was disappointing that Nyssa is just dropped into the story out of nowhere, I feel like that could have been bedded in a bit better. We could have had a pre-filmed slot of The Watcher collecting her from Traken. As it is you’re left wondering how this mute indicated to her that she needed to come to this brand new planet at this time. How did he transport her there?

The Logopolis based material feels a bit more detached and unrelatable than the Earth based material, which has a real buzz about it. Though I have to say, the companions do a great job of keeping the viewer invested.

I hope I’ll get used to Anthony Ainley’s Master, but so far he’s just a bit… crap. Sorry to say. The Master’s technobabble is particularly boring but the way he twists the knife with his final, utterly mad and cruel plan is deliciously evil and a great moment for the character.

As is possibly predictable with Bidmead, it’s all a bit over complicated. The plot falls off a cliff when The Master meekly looks at the entropy he has created and then, without any fanfare teams up with The Doctor, as if it was inevitable and everyone is just going through the motions. Huge plot points like these should make a lot more impact.

The excitement of the end, even if it wasn’t carried off perfectly did make for an exciting end to an uneven serial. Baker will be missed. I'm missing him already. But what a fiery performance to go out on.
