I watched Creepshow and Monster Squad quite recently, and I recommend them both.

Creepshow is an excellent homage to horror comics and has a few shudder-worthy, gross-out moments scattered through the anthology (note: they're more gross conceptually than they are gross-bc-of-well-played-out-special-effects; cut some slack, Creepshow came out in '82.

Monster Squad is more of a feel-good tween-ish horror movie; think Lost Boys over Hocus Pocus. Either way, between those two that should give you an accurate flavor for this genuinely-underappreciated '80s masterpiece. Complete with montage sequence and all.

I'll throw one more into the mix; Carnival of Souls. The original, not the remake. Creepy for its time, perhaps the twist might be a little predictable to a modern audience but if realizing the twist to a movie nullifies your ability to enjoy it, then boy you're missing out on all the fun and art of "how it's done." Carnival of Souls is a named influence, and when watched a clear predecessor of, several masters of horror who produced a number of the movies named here, by multiple posters -- George Romero, David Lynch, Wes Craven, etc.
