A friend of mine really adores Ace. I'm looking forward to meeting her (I just keep getting distracted -- I'm such a fannish butterfly (hence the name) and currently have nine shows that I plan to watch this fall).

My favorite is still Tennant, but Davidson is a close second in my heart and I have this big soft spot for Hartnell (and the Doctor's relationship with Susan, which makes me feel all warm and fuzzy inside... until the good-bye, which was just devastating and made me wonder if he ever got to see her again before Gallifrey went boom) and I like Colin Baker's Doc rather more than I think I'm supposed to.
