I was thinking more about this today, and to be honest, Sam was quite annoying as a character at times - and at the beginning he was a properly sanctimonious twerp until he got with his inner-Gene and chilled out a bit.
So I'm confident she won't stay quite as uptight, and having watched it three times now, I think she's OK.
I am equally ok with manly wine-pouring, manly carrying while swooning or drunk and throwing on sofa, or sitting in the corner flirting drunkenly. Alcohol, Gene Hunt and rudeness appear to be the only necessary common-denominator.
