Ironically Japan's animation scene was going through it's golden age in the late 80s with massive budgets being thrown at any animator with a vision which just happened to start burning out around the time the US's scene began to pick back up.
Akira is the most famous example of that, but there's also The Wings of Honnêamise, which the detail of the animation is so great and the level of design so great (everything from an electric fan, to books, to a freakin' popsicle has a unique design to this world compared to the real world) that it's honestly kind of scary to think it would even be possible to make a movie like that, it's literally one of the most impressive movies I've ever seen, anime or otherwise.
I rambled a bit but all I was trying to say is there's an 80s movie for almost every topic you can think of, from karate, the US air force, buying a farm, betting on horse racing, going to Florida, and trying to get laid.
To contrast 80s movies about real world things there's live action 80s fantasy, adventure and sci fi movies, all of which have a special magic, movies like E.T., Ghostbusters, The Goonies, Back to The Future, Gremlins and Who Framed Roger Rabbit.
The formula was usually the fantastical colliding with the mundane and the everyday, ie an average teenager hops in a time machine and goes back in time, to contrast with something like Star Wars, which was entirely it's own universe and while I've always loved Star Wars, I'm more fascinated by the fantastical happening in our world.
These movies also had very catchy, high concept premises ie "what if there were exterminators for ghosts?" or "what if cartoons were real?" but it wasn't just all about the story either, these movies also took time to create characters that we liked spending time with, for as great a premise as Ghostbusters is, it works so well because we like spending time with the Ghostbusters character themselves, same deal with Marty McFly, Eddie Valiant and Roger Rabbit.
In other words movies back then had more humanity to them, there needs to be a ghost in the machine, back then the special effects served the story, now the story serves the special effects and characters are just one dimensional stereotypes who check off some box on some "diversity" quota and that's it, no character traits, nothing that makes them feel human.
Rey in Disney Star Wars is a perfect example of characters today, there's nothing to her other than "is female" and "is strong", we don't enjoy spending time with her, she's not funny or interesting and she's not allowed to be sexy, contrast her with Leia who is interesting, has a personality ("Will someone get this walking carpet out of way?") and is allowed to be sexy with the slave bikini.
It's crazy how high the creativity was in 80s movies and how steep the drop off was, the early 90s still had a lot of hold over in the early part of the decade with movies like Terminator 2 and Jurassic Park (which was the last movie of that zeitgeist) but then things fell off hard, the only movie in that vein from the rest of the 90s that is on the same level is Galaxy Quest and maybe Starship Troopers.
