Okay, I wasn't entirely being fair. Most of them don't make him stop with puppy eyes. And I really do LOVE Donna, like, to pieces. Still better than I like Amy, in fact. I guess that what I was trying to articulate about Amy is that, not only is she feisty and willing to argue/challenge, she also doesn't seem to be easily sidetracked/awed by the fact that the Doctor is a time-traveling alien with ridiculous intelligence. Possibly because of his repeated misunderstanding of "five minutes." And somehow also I don't get anything like a romantic vibe between her and Matt WHICH IS A GOOD THING. Got enough of that for a bit, I think.
