Ten has been great so far, but as yet I can't imagine him supplanting Nine as my favorite (of all two Doctors I've seen!) Then again, this is only based on what I've seen of Ten so far, and it took me longer than three episodes to become as infatuated with Nine as I am now, so who knows how I'll feel by the end of S2?

I can imagine ending up loving them equally, even though it seems de rigeuer in the fandom to have a favorite above all.
