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

Previous Story: The Mind Runners

Wow, well that was a great conclusion to the last one.

So many interesting concepts and they were all handled really well; Mr Shift, mind running, a living planet that wants to use it's inhabitants as fuel. It had such a great atmosphere too, the world felt alive, literally. The Doctor was at his best here, you never really knew if he had thought it all through or whether he was coming up with his plans in real time. Leela and K9 were a joy to listen to in this story, especially the latter, he just worked quite well in this story.

There were plenty of twists and overall I think the scene towards the end was filled with clever reveals that I wouldn't have seen coming. My only gripe, and it is a small one is how there was an evacuation ship somewhere nearby in space ready to evacuate an entire planet, but that's a minor detail in an otherwise great story.
