I was alive then, and it was wild. Say what you want but it was a good time to be alive. Snapshotted in the films of that era: a mix of possibility and optimism, expansion and vibrancy - that started to decay in the 90s (grunge et al was a symptom of the 90s zeitgeist) and was completely demolished by the noughties.
Stranger Things is one of a few recent 'era remake' period pieces that capitalizes on demand for this kind of nostalgia.
In a strange way, I think hacker culture of the 90s continued the excitement of the 80s, but underground, when it had already begun to die in the mainstream. Who's with me on this? Or knows what I'm talking about?
In the 2000s I traveled to Asia and found the same sense of aliveness in the Sinosphere, unsurprisingly. That's gone from there now, too, replaced with something else in capitalisms' rapide marche. But I really want to know -- will this vibe ever return to the West?
Or, put it differently, where in the world can you now find that mix of fun, openness, positivity and possibility that was once alive in the 1980s? :)
At the time, of course, life was limited to dancing to disco and blasting classical on the Klipsch and gaining another few hundred feet uphill of mellow on Mt. Tam, but soon —maybe even by 2020*?— we'd be hang gliding in space colonies at the Lagrange points, eg https://nss.org/wp-content/uploads/Bernal_Interior_AC76-0628...
* after all, extrapolating from:
1903 - beginning of manned aeronautics
1961 - beginning of manned spaceflight
just imagine what another 60 years of aerospace would bring!
