User Reviews

Series 12 begins in style, improving on the failures of series 11
1 January 2020 | by rileyhdcSee all my reviews

On virtually every front, this episode improves upon the failures of series 11.

The three companions are more dynamic and nuanced, feel more important to the story, and are generally given more time to shine.

The monsters are more threatening and interesting.

And of course, the Doctor feels more... like the Doctor. Whittaker still hasn't been given the opportunity to establish herself as the character with a fantastic moment like all previous Doctors have, but she's definitely getting there.

The twist is also surprising and genuinely exhilarating and the end to the episode is interesting and leaves a desire to keep watching.

Let's just hope Chibnall keeps at this quality or even gets better and this series may well be worthy of the title of Doctor Who.
