I didn't fully realize it at the time (there were aspects of 90s pop culture I really didn't like when I was in the 90s), but a lot of good things happened in the 90s as a sort of comeback of 60s "hippie" ideals (like environmentalism, the organic food movement, world beat, multiculturalism, etc.).
If 90s nostalgia now picks up on some of those themes once again (go hippies! film cameras! 😂), I'm all for it!!
