I thought this episode was great and so fun! The song was a surprise but I really enjoyed it, what a great tune. I've found the big dramatic speeches to be too much in the past. For a time with Matt Smith it felt like the Doctor never did anything - he just explained how great he is then the baddies gave up. When he started singing though it was more like he was playing the goblin's game and buying time to find the master knot which I much preferred.

Ruby seems like a clever and kind person and a quick thinker. Brave enough to chase the baby onto the roof, didn't miss a beat when she got thrown into the song, worked out what the Doctor is at the end of the episode. Fantastic.

The Doctor looked really great dancing in the skirt at the start and I thought him and Ruby's band singer were nice touches for enby / gender-non-conforming representation. It felt like he's learned from Jodie's doctor to be more relaxed and fun.

There was a bit at the start where my family said "the Doctor's black" and I just cringed and was glad they didn't watch the previous episodes with Rose in. I really liked her and was thrilled to see a trans actor employed to play her. Really feels like they're stepping up and getting all sorts of people in the Dr Who universe.
