Grace Lee Whitney was a very cool chick, back in the day! She made a nothing part like Janice Rand interesting to watch. Majel Barrett just didn't have the chops for that. Nurse Chapel was lame in almost every way, except that she served Bones adequately. I loved it when Spock tried to wing her with the bowl of soup she made for him ... like he'd truly had his fill of her needy shit. It happened early enough, too, in that episode, where it seemed very much like that was the case.
