This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: The Pyralis Effect

This story marks the end of many things, it's the conclusion to televised Season 17 and while it was supposed to be aired in 1980, it was technically the last story produced in the 70s. It's the final 6-parter, the final story with Graham Williams as producer and Douglas Adams as script editor. It's essentially the finale to the 70s. While I wouldn't say it delivers on that, it's still a very solid story.

The animation is absolutely brilliant. While it was distracting at the start, seeing it switch from live-action to animated, you quickly get used to it. I think Tom Baker gives an excellent performance, in both the animated and live-action parts. This story is also an excellent display of the chemistry between Baker and Ward.

The supporting cast in this story are outstanding, Professor Chronotis is such a unique character and it's always fun to see a character that equals the Doctor. Both Chris Parsons and Clare Keightley are really enjoyable characters and help balance out the number of time-lords in this story.

And the scene at the end with Tom Baker, absolutely brilliant.

Next Story: Babblesphere

Season 17 Review: 8.5/10

Televised Season 17 was an interesting one, it had some of the greatest highs in Classic Who so far, City of Death and Shada, it also had some real lows like Destiny of the Daleks. It's not a season without it's faults but even in the dull stories the chemistry between Tom Baker and Lalla Ward gets you through. Douglas Adams as script editor also helps a ton, it's some of the best written dialogue of Classic Who.
