To comment on the "morals and philosophies" aspect of Star Trek, these were two credentials that, IMHO, were greatly exaggerated and even borderline imagined by some hardcore Trekkies and even perpetuated in the media whenever they felt the need to defend Star Trek against other franchises or to the general public.
Whenever Star Trek is compared to another franchise or is criticized, then here will come the whole "Star Trek made you think, Star Trek showed the world a better way, Only smart people like Trek, etc." It was amusing, I've even seen some say that "Star Trek showed us that the future was a better place and safer," of course, that is until the next week when the Enterprise crew or humanity were threatened out of existance. Someone even on another forum implied that TOS would ignite "hours and hours of discussion" amongst the youth of the time because TOS was just that engaging. Puhleeze.
As I say, these aspects are usually brought to the forefront by fans whenever the series is compared to other franchises. However, within the fandom itself it seems like the subject is not really discussed that much or even that important. You don't see fans going out and buying merchandise such as T-Shirts with "Star Trek Philosophies" written on them. People aren't buying model kits of "The Roddenberry Vision" and applying coats of morals primed with a glossy vision of the future. We aren't skipping over the battle scenes in the DVDs of the Trek movies or episodes just to get to the "really good parts" where they are setting around discussing the merits of peace and if war is a good or bad. Trekkies aren't dressing up in Trek costumes at conventions and re-enacting peace treaties with the dressed up Klingons at the conventions.
Hell to-the-fucking no!
The Starfleet and Klingon wannabes are gonna duke it out and engage in phase fire (as long as no one in public sees them.) They are going to buy props of phasers, reenact battle scenes with their model kits and playsets, put battle scars on their model kits, buy T-Shirts that have no other value than just having Picard's head on the front of their T-Shirts. That's how Trekkies really are! I should know, I'm one of them! We're going to comment on how cool battle scenes were, etc.
This is even reflected in the most popular episodes of Trek, most of which aren't known because they "brought you a moment of pause to think about the blah blah blah." One of the only few "intellectually engaging" episodes of Trek that I can think of that were hugely popular would be either "City on the Edge of Forever," and maybe DS9's "Far Beyond The Stars" (which actually would follow more under 'moderately popular,' maybe.) However, when it comes down to it, most of us enjoy the hell out of "The Wrath of Khan" or "First Contact," "The Best of Both Worlds," "Yesterday's Enterprise," "Balance of Terror," "The Year of Hell," or will even enjoy "The Trouble With Tribbles," an episode which to revert back to Dennis' prior comment, is probably up there with the most philosophically empty episodes, yet is one of the most popular and well known episodes in the franchise's history!
Now, to be perfectly clear, I am not saying that Star Trek in general is brainless or didn't have any of the elements we have been discussion. There are some good moments throughout with these elements, and Star Trek could be rather engaging when it wanted to be. I enjoy that stuff. However, when they started to get a little too heavy handed about "The future" and "This giant peaceful utopia" etc to the point that it became slightly cringeworthy, then all of the suddenly viewers and Trekkies started saying "Bye bye." Somewhat the same thing with DS9. Its ratings started off respectably but just kept dropping and dropping right off the bat. Why was that? Fans didn't feel there was enough action apparently. Here came the Defiant, the war arcs, and now DS9 gets praised by a lot of Trekkies (save for the first few seasons.) Did this save the ratings? Not really, though I think DS9 had a few other factors involved in its ratings slip, to be perfectly fair.
So here comes Star Trek 11. A surefire hit that was done by "outsiders" and the supposed "90210 Cast" that some of the haters like to say, and a movie that was about to make the rest of Star Trek seem even more cornball than before. So what was the ammo the doubters brought out? "Morals and philosophies." What's ironic is that there are underlying themes there, but they aren't spoonfed to us. Morals and lessons aren't always learned through discussions but through actions, or just living. You just have to "make the connection." However, because the message wasn't heavy handed or explained to the audience, those detractors will claim the movie is "dumbed down." Ironic.
Moral Of The Story - Star Trek isn't dumb or brainless, but it's not always as intellectual as some Trekkies would like to believe either.
