For me:
Movies [80s] Brazil, Repo Man, Mad Max 2, Blue Velvet, Platoon, Aliens, Robocop... too many to name, man.
Games [90s] I'm particularly fond of games from this era, be it art style, experimentation, whatever. Good shit.
Music (VGM & electronic) [90s] I'm an avid collector of Japanese electronic music from the 90s. A spend too much money on it.
Animation (series & movies) [80s/90s mix] Again, too many... Gunbuster, Patlabor, Ducktales, The Real Ghostbusters (lol), Moomin anime series (fuck you, it's great).
