I disagree. I VERY much love seeing films on Walt Disney opening Disneyland in 1955. I very much love seeing everything he said and did...and the guy died years before I was born. I can appreciate the nostalgia of films and music that were made LONG before I was born. You don't even need to be alive at the times that things were happening to get a nostalgic "feeling" or endearment to enjoy them.
I can watch a WW-II movie live Saving Private Ryan and I can get an enormous feeling of nostalgia and love for the people that lived through those times.
Why can't Disney be the same? Why can't Burbank market it's historic products to today's modern audience? Are these "modern" people not able to appreciate 100 years of incredible pop culture?
(Although it "does" make it hard when Burbank keeps placing "trigger warnings" on some of their incredible classic titles. I'm told that "modern" audiences have been conditioned to require "safe-spaces" now? Burbank doesn't want "Dumbo" to hurt any "modern" anxieties today?....I dunno)
Subjectively I am with you.
Particularly as an owner of all those Walt Disney Treasure sets with Leonard Maltin.
However Nostalgia is an experience where objectively, you were there for it. What you describe awouod be afficionado and when Professional, historians. Like the terms retro and vintage.
Walt had this love this way with The revolutionary war and American Frontier even though he was not there for it. He had Nostalgia for Main Street America. There is a difference.
And Walt knew this well. There is a reason one of the main lands and first and last impression one since opening day are Main Street USA.
We are saying the same thing. But for the sake of getting terms right, every generation has their own Nostalgia. Particularly odd to say you feel nostalgia while watching a film about WW II. As great and palpable as it is. That is not nostalgia. You were moved by a great retrospective biopic film. Maybe nostalgia for a family member who was there that you felt due to the film. Or pride and gratitude/patriotism. But not nostalgia for a war.
For a other example:
I have nostalgia of Mel's Diner at Uni as a place I was with my dad on my first visits to Universal. I know its a meh place food wise, but a thematic staple of a core memory. That is where my nostalgia for it is. Retrospective, I thi k it is cool that it is 1950s/60s themed diner.
My dad was teen
in the early 60s and had enjoyment of nostalgia for a place it reminded him of the same way the movie American Graffiti was made for those peeps even more so because the movie itself was a love letter of that nostalgia. Very evident in the film's tagline.
