Watching Korean movies from the 80s and 90s gives me a strange feeling..

It's an era I've never lived through, but watching movies from that time makes me think of my parents and gives me a sense of nostalgia for some reason.
Maybe I lived and died in the 80s or 90s in a past life....
Could anyone please recommend some movies from that era?
I recently enjoyed watching Peppermint Candy and Happy End.
I'm also planning to watch The Contact, Spring, Summer, Fall, Winter... and JYP (DMZ), what do you think of them?
