I'm not sure it's fair to suggest that those of us who disagree with the potential Walt, Vic relationship are doing it ust because we want to rag on Vic. I, for one, am not crazy about her character - that is true. However, why I really don't want them together is because (my personal view) of the lack of chemistry between them, sexually or otherwise. I know that I am in the minority on that because most watchers do seem to like the father, daughter relationship that they have built up on the show. I don't even care for that but, as I have mentioned, that is my personal view.
As for Vic herself, it has been said her character is much better in the books. I haven't read them so I can't attest to that. I can only go by what I've seen. In the first season, I really didn't mind her. She seemed strong with just enough personal issues. That was fine with me as sometimes the "strong, smart woman" can become just as cliched and boring. I'm not really sure why I started to dislike her more last season, but she just was striking my last nerve. I honestly think the boring stalker case did not do her character justice. It should have showed her vunerabilities, but also her strengths. For whatever reason, though, she just became more unlikeable to me. Unfortunately, that has carried over to this season with the possible Vic, Walt hook up. (As an aside, that scene in the bathroom where she was looking at Walt's scars almost as a turn on started the character off on a bad note for me.)
