Pulaski came off as a little too much like she was Doctor McCoy on the new Enterprise. I like the actress, she was interesting. I thought she was too hard on Data and I don't like the way they pushed that. She would have been more fun if she had become more accepting sooner.
I love Beverly Crusher. She's smart, feisty and she's one of the only people to argue with Picard. She was just there for Wesley and Jean-Luc in the first season, but when she came back she really became fascinating to me. She had a great sibling-like relationship with Will, she had fun conversations with Deanna, she had a great relationship with Data, connected with Worf (there's a great scene where they talk bat'leth training in "Quality of Life") and I'm very fond of her relationship with Jean-Luc. I think they had some of the most emotional scenes for either of them together: when Wesley left, when Jean-Luc was melded to Sarek and their scenes together in "All Good Things" are all some of my favourites.
