Airplane is a complete classic, but technically speaking made in 1979. I'll buy it still. Videodrome is also a wonder.
Indiana Jones is jewish power fantasy with lack of character progression, Return to Oz cannot comment and Cloak & Dagger is a run of the mill actioner.
>fun stuff to watch in so many different categories
I agree, but there's a difference between fun and good, one is a decadent candy that gloats on shenanigans and quirky perks but who cannot repeat the same formula many times because they depend on characterization, rare instances happen in which the director has most of the credit.
With good i meant a combination of all aspects like camera, acting, script, pace and atmosphere. In good decades you can pick 10 movies a year which all will be classics, the 80's have some years like that, for example 1987 and 1980, but in other years you almost solely depend on the soviets for drama and the asians for action, sometimes the Australians sparked a surprise. In my opinion Hong Kong was a monster player in those years to the point of molding the genre for the next decade (90's action style also called hyperkinetism) which was sadly degraded for corporate reasons in the U.S.
Sci-fi did reach a peak here, but not many classics can be picked apart from it unless i'm missing some scenes or we kick our standards down a notch or two to compensate. It's also the decade in which Hollywood went full on with the blockbuster and the feel-good oscar bait formulas which lack a lot of desirable script mechanics and character dynamics.
You brought a good point tho, it's probably the best decade for sci-fi. Robocop, Predator, Videodrome, Blade Runner, Empire Strikes Back, Terminator, Total Recall (technically a 1989 movie), but the big shots usually didn't bring big guns, the french were busted, the italians fell into the explotation antics, the brits were still in their cuck hole, the slavs still had some quality but fell into economic recessions (ruskies pulled through), japanese were experimenting a lot but only isolated products happened... who else i am missing, Germany wasn't that much of player since the 30's, and their best movie in decades was in the brink (also technically from 1979, Das Boot)
A more in-depth study should be made but in terms of the U.S. the 80's were a degrade from the 70's New Hollywood era, which was honestly a monster decade in cinema.
