I found the story engaging and easy to follow even without visuals. I was engrossed in the mundane and highly detailed dystopian world building. It is so perfectly summed up by mindless civilians singing "we are, we are all happy to work!"

The Macra go from being portrayed as these huge crab monsters hidden away from society to super intelligent parasites which burrowed into the control centre of the entire civilisation, keeping themselves hidden through a mixture of mind control and intimidation. This works extremely well... In fact I'd go as far to say that this has shot right up my list of stories I am most desperate to see return - one day perhaps.

It taps into a kind of political nightmare, the natural feeling that we could somehow become boxed in by our society and controlled by vitriolic powerful figures to live out their bidding.

We get some nice moments for our companion dynamics in this story. I love how Ben is tricked into doing the Macra's bidding and how Jamie and Polly handle this.

It is taking me a long time to make my way from season to season in this marathon - but stories like this is what it’s all about, rejuvenating my enthusiasm with the project. It is total classic.
