It's refreshing to be in contemporary 1960s London. Having only one companion in their home setting establishes Dodo a little bit further for her final story although I still don't feel there has been much of an effort made to flesh the last few companions (especially the female ones) out, they instead continue to fulfill the original companion's templates.

The Doctor suspects something wrong in the BT tower and somehow infiltrates it straight away. It would have been nice if they had tried to justify this. On meeting WOTAN the super intelligent computer there is a degree of intrigue, if perhaps it’s a tad pedestrian... but then suddenly we are transported to the "hottest nightspot in town!" The Inferno!!

We meet the bright young sparks Ben and Polly! These companions are exciting, contemporary and have a sense of play and banter between them. Seeing them meet and get to know each other is fantastic fun. For the first time since Barbara we are given a strong female character. I am glad they have finally re-written the rules for what the companions can be. They are SO cool.

I'm not quite sure why they kept getting the War Machines to drive into boxes. We get it, they are strong! But I like the idea that they are an unstoppable force. The modern day setting helps sell the story, as the team are able to cut to a pub where local citizens watch news broadcasts commenting on the situation. More of this please! The Machines rampaging through London look great.

WOTAN's control over humans is excellent - I love it calling the club and controlling Dodo who isn't the most inconspicuous person under Wotan's control. As soon as doctor catches wind of it he puts her to sleep to recuperate for 48 hours, if this is the production team writing her out of the show its a bit cruel. No actor should spend there last episode asleep. Would they have done this to Steven? Absolutely not.

Once the Doctor reprograms a war machine to foil WOTANS plan and bring the hypnotised people (including Polly) back to consciousness, he sets off. He mentions Dodo one more time... she has a message for him - no dramatic exit - she just wants to stay in London now. Despite that disappointment every part of any viewers being would surely be desperate to see Ben and Polly jump aboard, The Doctor didn't invite them - but Ben still has a key from earlier!

In terms of direction this episode is so beautifully shot, the angles are perfect, the show feels refreshed.
