I recall the day our first color TV was delivered to our home. It was in the summer of 1968, and we were boating and water skiing on our favorite lake when my Dad broke the news. We couldn't wait to get home and see if Spock's skin had a green tint. No such luck, but it made finishing out the original Star Trek series much more enjoyable.
These days I have little interest in the original series. Because I enjoyed TNG so much yet because of school and work missed many of the episodes, I bought the full 7-season DVD set. When Voyager came online I tried to see most episodes, but as my ex hated it, that would be her "girls out night" and she'd meet with friends while I enjoyed about 2/3 of the episodes. By now I've seen about 3/4 of the episodes, but am not enough of a fan to buy the DVD set.
DS9? No way. I've seen many of its episodes, and none seemed to have any of the same flavor as Star Trek should. I find it incredulous that it, too, spent seven years in production.
Star Trek: Enterprise returned the flavor of the original, and I love the fact that its setting was incorporated into the most recent Star Trek film which launched future movies onto the path of exploring an alternate universe beginning with James T. Kirk taking command of the Enterprise.
Yes, I'm a trekkie, although I'm not fanatic about it.
