The first truly great episode of series 2, and unsurprisingly it's a Steven Moffat outing.

There's a lot of positive stuff to say here - the story structure is twisty without being convoluted, Sophia Myles is pitch-perfect as Reinette, and heck, even Ben Turner's King Louis is pretty good. And of course, the clockwork men that harvest human organs are that combination of cool-yet-terrifying-in-a-childish-sort-of-way that Moffat excels at.

Tennant is at his swashbuckling best - I've said it before, but I really enjoy him as the romantic hero. And Rose apparently got all jealousy out of her system last episode, so there's none of that hanging over our heads this time around.

Speaking of Rose, I think they hit a good balance of enthusiasm for the adventure early on in the episode, constrasted with Mickey's nerves. It reinforces my notion that "Tooth and Claw" should have come later in the season, to show an increasing disregard for the seriousness of their situations. As it is, I think that one's still a bit of an outlier.

It's a little odd that Mickey says he got a spaceship on his "first go," but also references a previous adventure with Cleopatra. Maybe this is his "first go" to the future, rather than the past? I should really check to see if he and Rose changed clothes between episodes, but...nah.

They didn't bother shoehorning a "Torchwood" reference into this one, which is probably for the best.
