To say that an element of a work of art is meaningless because it is fictional is essentially an assertion that art can have no greater merit or significance than mere amusement.
If I want art, I go to the National Gallery, or go to Broadway or to a concert.
Star Trek has artistic elements, but its an entertainment fantasy franchise. That is what my 30 years as a fan has led me to. For all the higher-concepts and dollar store pop philosophy Trek fans has been peddling in for decades, on an artistic level, this is one step above a Saturday Morning cartoon (not that they make those anymore).
And I said this before, but what really drove home that point to me, was in the last season when Discovery tried to hard science a plot point. I appreciated the effort. Really. It was illustrative of how far our understanding of space has evolved since Voyager's bullshit science. But it was also completely out of place. Star Trek is predicated on bullshit science. Tachyons and Subspace. There is not an ounce of science fiction in this franchise that isnt window dressing. It's identical to Star Wars. It's fantasy.
And to that end, I hold it to the same creative standard as a work. I don't look for artistry here. I look for escapism.
It's not Star Trek, but there was an issue of this in Star Wars recently. Andor. Andor was a very good series. It was very deep. Very relatable. And it got high praise from a lot of media figures who never paid attention to the other 98% of Star Wars. And then those people turned into Mandalorian Season 3 and wondered what the hell were they watching, when they saw Lizzo and Jack Black embrace the cheese. Because Star Wars is fundamentally silly, and Andor was a mirage. There is no real art in Star Wars. It's escapism that sells merch.
I think we'd be better off societally, if we were clearer in demarcating where to expect art and where to expect entertainment. I didn't go to Ant Man to see compelling family drama or or feel like its relatable or something ridiculous like that. I saw it to see Scott Lang punch Kang in the Microverse.
Star Trek is every bit as ridiculous and one of the high points of SNW is that it is very self aware about that. Picard was too. It was just better at hiding it. Let's keep in mind the main character runs around in a "synth" body, whatever that is, and is the same person because of mind transfer, which is impossible, and his worst day recently is because a Changeling in a ship that was designed in a lab to look fearsome, made the Titan eat its own photon torpedoes thanks to a portal gun.
Or heck, super serious season 1, examining life and death, hot dropped a Borg cube on a planet, and it didn't devastate the continent . And it did it after it got attacked by a giant flower defense system. Why? Because it was spectacle for the audience.
Star Trek is a silly, silly show. And looking or art in it is a silly, silly premise. And you know who gets this the most? The actors. They alway seize on the fleeting serious moments.But they know the draw, and what they do thirty times as much, is silly fantasy talk. Patrick Stewart was a real trooper saying some of the things he said in Season 3, but you could tell through his acting he was grimacing sometimes.
