There are many parts of this episode that I love. The aesthetics are fantastic - the clockwork droids, the mixing of 18th century France and a 51st century spaceship, the visual of a human heart wired into the ship. And I love the concept of robots who become 'evil' but within the framework of their programming, which is something Doctor Who has explored several times (I was reminded in particular of Smile).

However, the one thing I don't like about this episode is the romance between the Doctor and Madame de Pompadour, and unfortunately that is the main focus of the episode. Because of this, I can't rate this episode any higher than I have, even though I loved the rest of it.
