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

Previous Story: Mawdryn Undead

Yikes, that was rough. In just 4 parts this story manages to be duller and more of a slog than the 12-part mostly missing The Daleks' Master Plan. I suppose that says more about Master Plan than it does this story, but I think the point I'm trying to make gets across regardless.

There's very little redeeming about this story, but I'll try anyway. Turlough is a much more interesting character in this story; he feels a lot less one-dimensional and you really sympathise with the moral dilemma. I enjoy how he's paired up with Tegan, as they both dislike each other at the start of the story. This leads to some great moments as Tegan begins to trust Turlough and Turlough begins to reconsider his dea with the Black Guardian, culminating in an epic cliffhanger.

Speaking of epic cliffhangers, the cliffhanger to part one was brilliant if a bit camp. I will forever remember that scream. I'll also admit I like the concept of this story, it's got generally interesting ideas all-round. I'm actually quite a fan of the explanation for the Big Bang, it feels quintessentially Doctor Who to explain the beginnings of the universe with a ship jettisoning unstable fuel and causing a chain reaction.

All that seeming positivity, and yet I've rated this story low and why? Because it's just so boring! Genuinely, it feels like nothing is happening. ever. I was surprised when it ended that a plot had actually happened because it feels like they were just endlessly walking around corridors the whole time. The worst thing to me in a Doctor Who story is not plotholes or canon inconsistencies, it's a lack of entertainment. And this story provided me extraordinarily little.
