So...anyone care to discuss the revival-era companions? As I said up-thread, I'm catching up after a long hiatus, watching things out of order. I'm trying to decide who was the better companion for the 11th Doctor--Amy or Clara. I can't quite put my finger on it but there's something I like more...not about Clara herself, but about her interaction with the Doctor. It seems more, I don't know, mature somehow. More brother/sister, less boyfriend/girlfriend. Have to wonder how that will change with a Doctor who is now visibly physically older.
One thing I have noticed is that the Davies-era companions were all normal women who were changed by their time with the Doctor, while the Moffat-era ones have been otherwise normal girls to whom extraordinary things had already happened, both tied to the Doctor before they had even met him.
Brief rundown of some random thoughts about them:
Donna--easily the most tragic of them, given that she'll die if she ever remembers her time with him.
Amy--the most abused, in that her entire first season was an object lesson in how dangerous traveling with the Doctor can be. Also, a redhead who was used as breeding stock by an alien faction...where have we seen this before...?
Martha--he didn't do right by her, hung up as he was on Rose. (Current one is always the best one, dude!) She should've been the toughest and most kick-ass. But, when she actually got a second chance with him, she realized she couldn't take it. (So why and how did she end up with Mickey ?!?!?)
Clara--hmmm...more of a younger sister than girlfriend type? Also perhaps the one with the greatest capacity for self-sacrifice, and the only one who's actually seen why the Doctor can never get too close to, or form lasting relationships with, any of his human companions.
River Song--not really a companion, but you could say she's the ultimate star-crossed lover.
Then again, I feel she's a bit like Martha, in that the Doctor doesn't quite seem capable of understanding her feelings for him or returning them (she seems to genuinely love him).
and not to forget...
Rose--the most fortunate. She got everything she wanted, including a version of the Doctor with whom she could actually realize her feelings (in all aspects). None of the other companions can say that.
cheers,
Gabe
