So, I rarely like a doctor for the first several episodes, my brain can't get past the last doctor. Took me forever with Smith. I always end up rewatching them later and loving them, it's just that I can't handle the sudden differentness well.
All that said, I really freaking enjoyed this one. I'm not fully in love with Ncuti yet, but I did really enjoy the episode, and LOVED the song. Oddly, the only Doctor I loved first off was Jodi. Ncuti is closer than most, though.
Also. That kilt. Meow.
Also loving the new sonic.

Forgot to mention, Ruby really reminds me of Clara in the best way.
