I think Julianne Moore deserved it, even though I don't really care for her as an actress.
It's one thing to act out a Psycho, but it does come naturally to some of the opposite sex, god knows I've dated a few.

I'm sure it works both ways, but I never dated guy's, so I can only comment on what I know.

Acting out a condition or disease, that's a different ball game, it's real life, and I can tell that she did her research on this one.
Obviously they dramatized some of it, after all, taking creative liberties is a standard process for the flow, but several key points that she made were so real, it was scary.
