It’s an awful lot of fun, this adventure with every Dalek ever and my personal favourite Master. It’s not just the quips or the impactful visuals, or even the bold hooks - of which there are many. It is the quiet character development of Davros which shines through everything else. You see more sides of him here than you get to in nearly any other adventure. He is so much more compelling in this more talkative and contemplative mode than the shouty, gibbering wreck we get in Journey’s End. The bookend with young Davros only enhances this. And I suppose is the closest we’ll ever get to I, Davros onscreen.

The device of the Clara Dalek is neat, it is a smart exploration of how the Dalek’s limited and clearly controlled vocabulary shapes it’s character.

The way the main plot is tied up is almost perfect in concept, but in its realisation it comes across sudden and disconnected, in an otherwise pretty stellar story. A fantastic opener though, and for this viewer a much more promising second leg to Capaldi’s era.
