I can appreciate that. I used to love Mel Gibson's movies, but since his publicly poisonous debacle, the thought of him sort of turns my stomach and I haven't watched any of his stuff since.

But for the most part, characters are much more "real" to me than the actors are -- in that I've been given the opportunity through a movie or TV show to intimately know a character in a way that's rarely possible with the actor playing the part (nor, generally, do I want it to be). So unless an actor does something truly deplorable or mortifying in a very public way, I'm not likely to have nearly as strong feelings about him or her as I do about the characters s/he plays.
