I have said several times in the past that my main problem with Pulaski is that I felt her character was too sober (in the emotional sense, not the 'not drunk sense') and nonchalant for my tastes. When I watch season 2 I have the feeling she reacts to almost everything with a slightly amused smile. (I have expressed this in the past by speculating that whenever she gets married she already pencils a 'divorce by this date' into her personal calender) A more favourable interpretation would be that she's even-tempered, I suppose.
I also maintain that she didn't pair well with Troi, which further isolated Troi (though that's not the fault of Pulaski alone, it's the fault of the show runners who thought more than two female characters would be 'too many' and had little interest in developing the ones they had, I do wonder whether I would have thought different of Pulaski if alongside her they had also introduced a replacement for Tasha with whom Troi wcould be friends)
But I definitely think that their initial attempts at making her look like "McCoy in a dress" didn't do her character any favours and painted a wrong picture of the way she was portrayed. Her treatment of Data came across as bullying (but, as I said, they dropped that quickly) and the first episode makes it initially seem like she went to get a drink before even meeting the Captain (which defeinitelly didn't endear her to me) when instead she was only in Ten Forward for the benefit of Troi to discuss her surprise pregnancy in a more relaxed atmosphere.
Not so much about the character, but the actress...
I have said several times I think Diana Muldaur would have made a very good Janeway, better than Mulgrew (at the very least with a more pleasant voice).
