Three formative things from my childhood/teenage years: The books of Rosemary Sutcliff, the folk-music inspired output of Clannad, holidays spent in Scotland.
To be honest, I also rate Survival
pretty highly, so The Eater of Light
would have had to try pretty hard for me not to love it. I'm not sure I can even remotely claim to be looking over this story with an unbiased eye. I loved it a lot. It does reassure me that The Teenager also loved it however, despite considerable sceptism about Rosemary Sutcliff (occasionally I give her the books, she tactfully ignores the gesture), and no memories of Scotland (or Survival).
She does like Clannad though, but I'd argue that the music here, while definitely folk-inspired, is not particularly Clannad-ish.( Spoilers under the Cut )
I loved this. It hit me in all my nostalgia weak points and handled this particular TARDIS team, which I already liked, perfectly enough to convert me from well-disposed to a fan. The Teenager said she thought it might be her favourite Doctor Who story. I'm not sure I'd necessarily go that far (this is no Blink!
) and I'm almost frightened to see how it would stand up to a rewatch because I'm very aware that external factors were effecting my ability to think critically about this. But on a single viewing, I'd say it was my favourite Twelfth Doctor, Bill and Nardole story.
