(Incidentally, I am a hypocrite. I rolled my eyes at many, though not all, of the Rose references in s3, but squeed about the Martha talk in Partners in Crime, and now the Donna reference (the second one in a row if you count the one in the last special, which was more indirectly phrased but unmistakable, aka "and sometimes, they forget") made me very happy indeed.)

*raises hand* Yup, same here. And I'm only mildly ashamed about that. Oh, who am I kidding, I'm not ashamed at all.

I too liked seeing Captain Magambo, and that she had priorities other than the Doctor's, but not treated as wrong. I'd love to see Privates Nathan and Barkley again, that'd be very nice.

Lastly, yeah, I guess Christina and Ten are too similar to work for an entire season; at the same time, I liked their dynamic very much indeed here, and thought they got some wonderful dialogue. She was excellent.
