Oh, I know. And I know that Billie Piper can act, so it's not a slam on her. Aside from Martha, (and I haven't seen the current companion(s), it seems as though with Rose and Amy, The Doctor has been travelling with rather immature, selfish, people. It's rather annoying (and, it seems to me, somewhat sexist) how both Mickey and Rory were the dutiful boyfriends when their SOs are off travelling the universe for some unknown amount of time (gah, they could have at the very least called), and facing whatever, for women who seem to rather prefer being around a strange man in a police box. No matter how wonderful someone else is in other respects, I'd show someone the door if they treated me like that.
