I'm 24, currently two and a half quarters away from a BS in accounting, and grew up watching TNG vociferously. My Dad is a trekkie, and starting with The Big Goodbye he taped all the episodes (mostly first-run), so whenever I went to visit him all we'd do is watch hour after hour of Star Trek together. Or by myself until the wee hours of the night
My favorite characters during TNG's run were Tasha Yar and Ensign Ro, but about ten years ago I was looking back at my favorite episodes, and I realized that Riker has a strong presence in each and every episode I love, so I realized that Riker has been my subconcious favorite all along! I also had a little girl crush on Wesley, and then I got a little older and hated him, and now I'm 24 and have a little girl crush on him again, but I'm old enough now to not take it seriously. I loved Beverly's red hair, and was disappointed that it has gotten blonder and blonder but oh well, she still looks good! I never realized what an impression Picard left on me until watching post-TNG Star Trek. I enjoy a lot of DS9, VOY, ENT, and the movies but I really miss the efforts to solve problems without violence.
I haven't gotten to watch much TNG in quite a while, the last time I visited my Dad and had enough time to watch his Star Trek tapes was in 1998, and I used that time to catch up on DS9 and Voyager. So I think the last time I saw a lot of the episodes was in 1996, but I feel like I know the episodes well, having seen them so much. I miss them, and I'm trying (and failing) to save up to get the DVDs and a DVD player. I have seasons 4 and 5, but I can't decide which season to get next because I love them all so much.
No syndication available for me; I don't have cable, don't get reception, and only use it for tapes, dvds, and videogames.
