I have always wondered if Gellar would mellow with age. In the past she has been very outspoken about not attending events as it was "not her thing". She has done the San Diego event on a few
occasions, but San Diego is used as a press junket for so many TV Shows and FIlms, her appearances have been contractual to promote the show or film (her words and not mine).
Hopefully, she will realise that she still has a fan base and a big one at that. Maybe she will do one or two a year as I think she would be big business if promoted correctly.
