Over the years (but not so much recently) I find that anyone who watches the Star Trek shows prefers the newer shows to the old ones, and specifically STNG.
You might want to go up one level - to the "Main Bridge" and look where the most threads and postings are. Doesn't seem to reflect what you are saying here.
Over the years and until the new movie, plus the end of the STNG films, the STNG forum was a lot busier. When remastered started airing and Enterprsie and STNG was not, that's when the forum started to grow. Plus both the TOS and STNG forums lost threads and viewings from various "prunings" in recent years.
It apparantly didn't bring enough - the Franchise is dying hence the reboot. Check it out:
There's no question that fandom has shrunk over the years, but TOS and specifically STNG gave birth to over 700 hrs of shows plus 4 movies. Many of these award winning (STNG with over 70 plus emmy nominations) and many respected by fans if not a wider audience. The reasons for the lack of interest has been speculated on for years, and I won't go over them all, but whatever form it took, I knew the franchise was not going to disappear, and it hasn't.
You give an excellent example. Spock was alive denying and dealing with feelings like we all do. Data was a robot with an emotion chip. Lots I can relate to there - NOT.
Doesn't matter, Data is an android and Spock an alien, both SF standbys designed to make a point. No one on Earth is Vulcan, but he was used as a metaphor for what human beings go through. Data explores similar territory in a different type of character, the idea that Data would be a Spock clone never materialized and Spiner made the role his own. We were not only able to see similar METAPHORs for what the human condition is but also with Data we were able to explore the relationship between man and machine, and what really is the difference between advanced AI and humanity which resulted in the writers guild nominated "Measure of a Man" and of course, lots of other stories. Despite being an android I saw lots of fans share a sympathy for the character, even more than one for the unemotional Spock, since he didn't really care to be us.
Picard, Riker, Troi = BORING. Hollow, passionless, poorly constructed meaningless character whom nobody gave a crap about.
Opinion of course. I found Riker to be a good character, though his role on the ship didn't allow him to be the center of attention as much as some other characters. Troi was not one of my favorite characters, but I do think its important to show that what's going on with us psychologically is at least important as what goes on physically. Picard was awesome, my favorite captain, and I know he won over legions of fans both in terms of acting, character, and dimensionality. Some women even thought he was sexy, go figure.
Speaking for myself, I don't generally have to empathize or relate to characters. I don't really do that with fiction. I don't ever feel a need to be any of them, but themes, writing and meaningfulness interest me, and all the Trek shows have that to some degree. Good for you. But I find being preached to and entertainment that is very cerebral also very boring. It seems like I am not the only one either. Please try to remember that if you want someone to skip a football game in favor of watching Star Trek - they'll have to make it more entertaining and exciting than the football game. TNG wasn't. Its even tougher when it comes to shelling out $10 to see a movie. It better entertain and effect our emotions to get us to watch it.
Funny, but TOS was far more preachy in its plotline construction of creating "straw" cultures to tear down in order to teach them human moralities. Don't really have a leg to stand on there. STNG tended to leave things more open ended and even left the prime directive intact once in awhile. It
certainly had a point of view, but it was presented so you could think about it and debate rather than be dictated to. I do like to be intellectually engaged when watching fiction from time to time (insert mild sarcasm)even though a good action sequence can be a lot of fun.
Actually STNG's ratings increased almost every year till it avged almost a 13, and 17 million viewers an episode. Lots of people would make time for one of its airings just as those who discovered TOS in reruns did when syndicated markets started showing it in early evenings in the 70s. In short it became a phenomenon in its own right.
