An important aspect to an actor is their vocal qualities. I just don't like the voice of Diana Muldaur. I didn't really care for it in TOS either... something about the nasal quality. So, Dr. Pulaski's voice came off as annoying to me. That coupled with the direction she was given, it didn't work for me. Beverly Crusher was a welcome sight when she returned in Season 3. But I still wish we'd seen a "transfer" take place, with the two of them interacting. Pulaski at least deserved that.
