Yeah, maybe that's cause we don't have nostalgia for any of the adapted properties they keep choosing over and over. The original star wars came out in 1970-something. Maybe some older Millennials have some nostalgia for the prequels, but even most of them tend to know that it sucks pretty hard. I feel like a lot of the millennial childhood movies, the nostalgia-bait, is gonna be stuff that are bad remakes or sequels of older movies. Gen-X had predator, Millennials had alien vs. predator: requiem. Maybe early Millennials had heathers, but mostly, Millennials have mean girls, which recently got a 1-to-1 musical remake, which wasn't that good. Last two times they've tried to adapt avatar, it's been pretty bad, as well. I just don't have supreme confidence that anyone will really understand the appeal of any of these works or realistically be able to replicate them.
I think probably a primary driver of this is that a lot of these works' appeal is rooted in their specific aesthetic, and hollywood as of late has felt very homogenized to greenscreen soundstages where everything is set in a concrete cityscape with overcast noonday lighting, because all the non-unionized CGI patsies are subject to a bunch of crunch time pressure where they just have to churn out garbage over and over. Also not helped by the amount of this which is done overseas, and can't actively take any co-ordinated input in the middle of production. Mergers, leading to ballooning budgets, leading to shittier, more controlled, more generic products. Same shit has been happening in gaming, too. Easier to sell a committee decision on a remake, adaptation, or sequel, too, something that's "proven" as a property, instead of an original IP.
That's not even really to talk on how many Zoomers probably have nostalgia for early youtube videos, and shit like that, rather than mainstream movies or franchises. They don't need to watch a remake of like, an old markiplier video, they can just tune into him doing basically the same thing he's done for the last 15 years if they want a shitty nostalgia hit. I don't need a remake of homestar runner, they're still releasing shorts that I can watch occasionally. You can watch most of the same old guys because they're still doing the same stuff they used to do. For the most part, anyways, lots of them got cancelled for being shitbags, or have had severe mental breaks. Still, point stands that, at the lower end especially, I can just go online and watch a bunch of amateur artists destroy their craft, I don't need the movies or TV for those niche hits anymore.
