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

Previous Story: The Perfect Prisoners - Part 2

Well I thoroughly enjoyed that,

This story serves as the introduction to Romana, who I think is brilliantly played by Mary Tamm, she immediately steals the show by being able to match Tom Baker's bold personality and her character in general is a nice contrast from Leela. The introduction for the White Guardian is well done and sets up what is Doctor Who's first real series arc. Tom Baker feels especially vibrant in this story and you can tell he's strongly settled in the role.

I really like the planet of Ribos, in these short 4 parts, it's fully fleshed out as a planet and a culture. I've been noticing that a lot of the locations in recent seasons feel like genuine places. Especially in this episode, the costumes and the sets are wonderfully designed and the culture feels well thought out. And Binro, so much to say about Binro. The conversation between him and Unstoffe was genuinely heartwarming and his death is the first time I've genuinely been sad at the death of a side character so far.

The whole concept of the story is fascinating aswell with a conman trying to sell off a planet to an exiled king. All the twists and turns make for a story that never loses your attention.
