I don't think it's just Trek.
I've got two children still living in the house. One is 15, the other is 10.
Trying to get them to watch anything with me is like pulling teeth. What they like is few and far between. Comic book movies, Ghostbusters, Star Trek, nature shows, sitcoms, Star Wars, and on and on, they just won't.
So what do they watch? YouTubers, TikToks, things like that. It infuriates me, but that's also pretty common amongst the younger generation. The good news? They might eventually find their way to Trek.
My oldest daughter, who's a grad student at UF, just asked me to make a list for her of how to watch Star Trek in chronological order. She wants to get through as much as she can before going on the Star Trek cruise next year with me and her mother.
Likewise, my youngest kids will often get pulled in when I just have it on in the background. My youbgest daughter loves the music from Subspace Rhapsody. My son enjoys Lower Decks when I have it on.
So, maybe, in a few years they will come around. But what Frakes is describing? That's not new. When I was in the sixth grade going to conventions in the 90s, I barely saw anyone there my own age. It was all adults. And yet, those fans must have been somewhere because there are a LOT of people watching Trek now who are in they're 40s. But if you asked Frakes that same question in 1996, you'd have gotten the same answer. So... we will see what the future holds. But certainly, anecdotal evidence isn't reason to stop productions.
And as far as reviews of Prodigy go, how many 9 year Olds are leaving reviews of anything on Rotten Tomatoes or IMDB?
Remember - Not everyone who watches and like Star Trek is going to bother to go to a Convention. In my day, you often went to conventions just for the Dealers Room, or to see some 'lost'/'hidden' footage. Seeing an actor or two talk in person was nice; but honestly, for them it's a gig - and yes, they LIKE fandom because it keeps them employed, and they may even like a lot of the work they get to do - but they ARE ACTORS and even in public they have a 'persona' they project; so you're never going to really get to know them or be real friends at a convention (and yes, there's always an exception here or there.)
But my point?
- With all the online shopping available, you DON'T need to go to a Convention to find that piece of fandom you want (be it a prop replica, costume, etc.) <-- You can search and find it online somewhere and yes, it may take some work to verify it before you buy (where possible), but it can all be found from your house and sent to you.
- Same with most 'hidden/lost' footage. Some Youtuber or Tic Tocker is going to find it and post it, so no need to leave the comfort of yo9ur house.
The people who still go to Cons are the true 'hardcore' fandom <-- And Paramount (and Kurtzman) isn't too worried about engaging that fandom because they STAY engaged in their own way. As long as Paramount and Kurtzman throw us an occasional interesting easter egg or nostalgic scene, we're good in their eyes. Even the 'hate watchers' ARE watching, which gives them numbers - Hell, even the pirates have a source that still paying something so they can get/distribute via 'Pirate' means.
So yeah, it's why we have so much different stuff across many Star trek eras (including the new 32nd century one which is continuing with the SFA series.) They ARE trying and probably reaching 'new' fans.
Remember A LOT of TOS fans DESPISED TNG when it hit the airwaves. Many of them DID stop watching it while others hate watched and if you told them "Well, TNG is creating a new younger fan base that really enjoy it..." in 1987/88 they would have told you you're crazy.
Believe me, the current batch of Trek offerings is creating/reaching a younger fanbase, who will see many things from it as 'their Star Trek' and be raging at the (in 20-30 years or whenever) 'Nu Trek' when this current cycle ends and Trek is dormant for a few years.
^^^
And I say 'a few' because if you look at the franchise history, the longest it lays 'fallow' with no new big or small screen offering of some type has been 4 years.
If STAR TREK were still only seen by original TOS fans (like me and I was 6 when I fell in love with it in 1969), Paramount wouldn't bother spending all the money it has been spending tom make new Star Trek.
