I was 14 and already a Star Trek fan. It was a new Star Trek show, so I was there. It wa pretty good from a story perspective. Definitely better than the other cartoons of the day. The animation was typical of television of the era, so I didn't expect anything better. I did wonder why they couldn't use the "real" Star Trek theme music. Since I can still whistle it to this day, it must have made an impression.
