Bit behind, so I caught up on the last four episodes this weekend:
I rather liked this one, with the real time plotting keeping everything at a hectic pace. Yeah, the trivia question door locks were pretty silly and I'm not exactly sure how the engines fired up at the end, but the tension kept it entertaining. Perhaps, though, the Doctor should have spent less time yelling "I'll save you!" and got on with the actual saving.
HUMAN NATURE/THE FAMILY OF BLOOD
This could be the best overall two-parter the new series has seen. I'm glad the Family weren't killed as they might be the most interesting new villains yet. Creepy, darkly humorous, and poised for a comeback (the sudden switch to the first-person omniscient with Son-of-Mine sounded like he was reflecting on the events from some point in the future).
My main quibble (apart from the Doctor's new mirror-putting ability and his dropping Father-of-Mine off in a random sewer somewhere) is that the "Come with me" card is being played way too much these days. In context, it makes sense that he would ask Joan to go traveling, especially since it seemed like it was more to ease her pain than his. But since he's done it so often lately, it robs the offer of any weight.
I don't mind the vengeful edge of the Doctor since he's now reeling from both the loss of his people and the loss of Rose. However, I'm hoping that this gets thrown into sharp relief if it transpires that he really isn't alone and that some of the Time Lords have survived (other than the Goateed Chuckler, that is.)
As a firm believer that the hedge animal scene in The Shining is the scariest thing Stephen King ever wrote, I am inclined more than most to love this episode. And I did. Sure, I wish we had never seen the teethy grimaces of the Angels as the blank stares were creepier, but that is a minor nitpick of a story that was so well executed. I completely agree with Meister that this is how you do Doctor-less Doctor Who and that Torchwood's writers should watch it repeatedly before the second season of that show begins.
Speaking of Torchwood, I'm very interested in finally seeing Captain Jack's return to the TARDIS next week.
