When Heather Tom left the show, I thought I'd never accept anyone else as Victoria - but I was wrong. This actress has grown on me and I think she's brought a softness and sensitivity to the character that Heather never did. I agree she has been Miss Mope lately, but I wouldn't blame the actress - just the situations she is supposed to be responding to.
Heather's Victoria was hard and brittle and could be very cruel. I never liked the way she treated Nina. I LOVED Ryan and Nina together and thought they were adorable. When Nina lost their baby, Heather's Victoria was mean, spiteful and snarky. When Heather's Victoria lost little Grace, Nina came to see her at the hospital and told her that she knew how she was feeling.
I suppose I could argue with myself and say that this was the fault of the writers as well - but I'm not so sure. I believe the actress herself can do a lot to shape the character.
