10 Most Overrated Doctor Who Episodes

10. The Zygon Invasion/The Zygon Inversion

Let’s get this out of the way first – we don’t have a single bad word to say about Capaldi’s impassioned anti-war speech in the back half of this two-parter. It remains one of the absolute highlights of Twelve’s run, and watching it back, it’s clear why Moffat had the confidence to give Capaldi the show’s first one-hander in that very same series.

But beyond its final 20 minutes, The Zygon Inva/version spends a lot of time treading water.

It finds itself in the rather awkward position of clearly needing two parts, but also not having quite enough story to justify the double runtime. Jenna Coleman’s turn as Bonnie is enjoyable and she’s clearly having a lot of fun playing the villain, but the UNIT stuff here is weaker than usual, and tends to plod along. A lot of the first episode feels like padding, to the point where it's kinda difficult to remember – this is an hour-and-a-half long, but our memory of it is the final half an hour. Generally not a great sign.

It’s still a good story, but we do think people tend to focus on that one fantastic scene when they rave about this one.
