Personally, I'm glad there was a season 3, regardless of the quality of all the episodes. I personally liked several of them, although in some cases, I did not see all of them until reruns started a few years later, when I was older. Anyway, with a third season, it provided ST with more stories to further established the ST universe and the relationships between the crew. It probably also increased the likelihood of reruns and the eventual rejuvenation of Star Trek. So good, bad, or indifferent, I'm glad Season 3 happened.
