Star Trek was one of those shows that had me glued to the TV every week as a child. I'd lay on my belly on the floor right in front of the TV, chin in my hands, trying my best to peer through the snow because the station didn't quite come in all the way. I idolized Spock, made my fingers do the Vulcan "V" and worked to make my left eyebrow go up when I found something "fascinating." I idolized the logic in the character, and imitating it gave my very emotional, sensitive, creative brain an anchor. I still watch reruns of any of the Star Trek shows, and of the original series, I've seen each episode, oh, about 25 times, if not more.
Majel Barrett played the sickbay nurse, and she suited the part well. She did her job. I never knew until many years later that she was the wife of Gene Roddenberry. When she played Deanna Troi's mother on ST:TNG, she expanded her acting and let loose a bit of eccentricity. The small parts that she played always stood out.
The Roddenberrys took us 'where no man has gone before' and it will be awhile before we catch up to them. They kept our eyes ahead and on the future.
