I really enjoyed the plot of music disappearing and it was set up well. Maestro sets theirselves up as a great villain when we first meet them and it continues through the rest of the episode. They’re creepy and enjoyable. The music battle scene was brilliant. I love that Maestro is the child of the Toymaker. We already knew that his influence would be around in this series. The series arc is laid out with them. The Doctor being scared of them is great. We never see that happen but I like that he’s able to overcome it. Ruby is great in here as well. There is no major critique before the ending.
