I REALLY don't want to seem to be mean or anything, but could people please stop mentioning David Tennant? I can't stop thinking about the third season... (which is sad 'cause I'm [along with most american fans] not able to see it yet, unless it's on You Tube...)
Anyway, my favorites (scince I didn't really mention them...) would have to be William Hartnell, Tom Baker, Peter Davison, and David Tennant (of course), but I have favorite episodes with all of the various actors.
It's time I've started coming back here more often.
Insanty-It's a family thing.
