I was 14 and already a huge TOS fan. I'm not sure when or where I first heard of the forthcoming series, but it could have been NBC promos. My first exposure was "Beyond The Farthest Star" and then "Yesteryear." At the time I thought the show was light years beyond what else was being done in animation, and while I loved it I still didn't think it was on the level of TOS. I noticed its limitations back then, but I overlooked them because I was so excited to get new Star Trek adventures as well as getting to see new ships and new exotic aliens.
