The fun is toned back just a tiny bit for this one, but not the sillyness.

RTD continues to show that this is the same show that started 60 years ago, referencing Susan and having a scene that directly echoes one in "Pyramids of Mars"

The Maestro is an incredible villain, the stakes are high with another enemy as powerful as the Toymaker and they certainly carry the menace needed to match up with the Toymaker. This episode set up even more for the future and the Doctor practically brought a demolition crew to the fourth wall at the end of it. So many plot threads I'm concerned it won't live up to it.
