I liked the fact that Crusher was fresh and original. Pulaski was a female version of Dr. McCoy... a crusty old transporterphobe who enjoyed teasing the second officer (Data). Nothing original about Pulaski at all. But Crusher was the first time we saw a working single mother on a Starfleet ship, who happened to be a senior officer. The fact that that aspect of her character wasn't fleshed-out well or well enough isn't her fault... it was on the writers and producers. Gates did the best she could with what she was given, IMO. And she was hot.
