This episode’s shock and awe worked on me. Davros as a child! Missy stopping planes! The Doctor on a tank! Every Dalek ever! There’s nothing subtle about it, but these big bold ideas enable effective storytelling. The hand mines are a very clever conceit. And being a loose sequel to Genesis of the Daleks, gives The Doctor the motivation to kill Davros as a helpless youngster.

Perhaps the best thing about the episode is the way in which Missy is used as a protagonist and Davros as an antagonist. I prefer this more cerebral , reflective, talkative Davros. He is far more compelling than the megalomaniacal shouting dictator from 2008. I like to think about him as a duplicitous, creeping villain. Missy goes to lengths to show that she is still evil, she hasn’t gotten cosy, at the same time she is teaming up with The Doctor in a way not seen on screen for decades. Michelle Gomez is bags of fun and lights up the screen. A fantastic contrast to The Doctor, Clara and Davros.

The softening of The Doctor was much needed and I am feeling a sense of relief having a bit more fun back at the centre of the show. It doesn’t mean that he is not dangerous, he clearly a complex character in this, but it finally feels like the right balance.

If I had to find fault, it would be that Missy and Clara’s deaths do not feel permanent or emotionally real. I would have fathered they saved this for the finale, or later in the series, where a viewer could possibly believe it could happen!
