Crusher.
There's only one way I can think of to describe Pulaski.... McCoy-knockoff bitch.
That's how she started in her first episode, and (unlike some others) I honestly don't see how she changed at all throughout the season.
I think Crusher had more personality. She was kind, but she had her limits. She was warm, open, and comforting, but wouldn't take crap from anybody.
LOL that's pretty much how I would put it :P
For some reason Pulaski reminded me of a grumpy substitute teacher I once had.
On the other hand, I don't think that Pulaski was handled good in S2. The reason for Muldaur's departure was due to the backstage politics. There was a lot of backround dirt that happened throughout the series. Also the wardrobe/ makeup people did make her as haggard as possible too. Her departure was sad because she was the last TOS actress around on a permanant basis. Her character had much more depth and past to offer. She was somewhat a mystery. She was good with Picard because she would stand up to him. Crusher would eventually wilt like she did in First Contact. It took a "primitive" (similar of Pulaski) to point out that Picard was barking mad and trigger happy. Crusher had a medical duty to make sure that her Captain was rational and fit for command. She wasn't there to drink the Kool-Aid with him.
