I'd say it's a decent one. It doesn't have much going for it, but it's still very enjoyable. The Master + Rani duo is truly iconic.

It's a great caricature of the world we live in, whether in terms of politics, culture or voyeurism. The episode manages to be so rich in what it says. Obviously, a lot of the points are exaggerated, but I really enjoyed it.

It's a shame that the story goes in all directions and makes understanding the episode rather complicated. Otherwise, the Cybermen are terrifying and the ambition is clearly there.

So... Even though I always have a good time watching it, I have to admit that when I plug in my brain, it doesn't work too well. On the plus side, I love the concept of this new Doctor, seeing how terrible regeneration can be for a Time Lord, juggling periods of euphoria and depression. But the rest... The acting isn't up to scratch all the time, the story is really lambda, I wasn't touched by the characters present and the ending makes me want to tear my hair out. The potential is there, but there's a certain taste of unfinished business.
