The 80s might be my favorite decade for movies.
I can see the argument for the 70s and 90s having better serious dramas, but when it comes to action-adventure/sci-fi/fantasy, the 80s can’t be topped.
Empire Strikes Back and Return of the Jedi

Indiana Jones Trilogy

Blade Runner

Rocky 3 and 4

Ghostbusters

Beverly Hills Cop

Back to the Future

The Goonies

The Terminator

The Last Dragon

Big Trouble in Little China

Aliens

Predator

RoboCop

Bloodsport

Coming to America

Die Hard

Who Framed Roger Rabbit
In terms of music, the 70s through the early 80s >>>
Stevie Wonder, Marvin Gaye, Isley Brothers, Chaka Khan, Sly and the Family Stone, Parliament-Funkadelic, MJ and Prince in their prime.

Shout outs to Lakeside, the Gap Band, Slave, Zapp and Roger, the Time, Cameo, and the SOS Band.

There’s a reason so many rappers sample their beats from that era.
80s were the goat decade for comics IMO.
Jim Shooter Marvel >>>>>
Marvel started falling off in the 90s after the image crew left, which led to the comic crash in ‘96. Not long afterward, the anime boom hit, and manga has been styling on Marvel/DC ever since.
The 90s were the best era for gaming though. The 16-bit ekazan.
