Critic Reviews for The Zygon Invasion

This is the point at which I usually gripe about all the things in the episode that didn't really make a whole lot of sense... But for me these strange quirks actually added to the interesting weirdness of the episode.

The Doctor Who team may take two years to close a plot hole, but they get there eventually.

The return of fan-favorite aliens the Zygons would have been enough to get most viewers' hopes up, but when you throw in UNIT, a seemingly-resurrected Osgood and another appearance of the Doctor's electric guitar, you've got a classic in your hands.

It's an episode designed to teach, and does an excellent job of making the parallels without coming off too preachy or wishy-washy on the subject.

A bold enough turn in the story and makes for a juicy hook for next week's installment, but, again, it felt more predictable than I would have liked.

It's a story in which the "status quo" is really, really weird -even though it ostensibly takes place in present-day Earth. And it's hard to tell what exactly would constitute a happy resolution of this situation.

Just when I've lost almost all hope for my show... we get an episode like this one. 'The Zygon Invasion' is incredibly good science fiction storytelling. Incredibly good Doctor Who.

Easily the best episode of this series so far.

The splitting of the action between three locales diffuses rather than reinforces the tension, especially as so little happens to Kate.

And with that brief, impassioned speech, "The Zygon Invasion" arguably became the most important Doctor Who episode since "Vincent and the Doctor" tackled depression back in 2010.

Nov 2, 2015 | Rating: 5/5 | Full Review…

"The Zygon Invasion" was full of dark, cramped corridors, alien shapeshifters, and some genuinely unsettling scenes. It was another strong entry in what's shaping up as one of the strongest seasons of the show in years.

It's a fun ride and there's something satisfying about gradually realising what those crafty shapeshifters are up to, but it doesn't really help the drama when genuine twists and surprises are thin on the ground.
