The year itself sucked ass, of course. but I always argue that 2004 was the year we fully and totally switched over from Gen X to Millennial mass culture and became fully submerged in millennial zeitgeist as the default. Highlights include:
-Mean Girls and Napoleon Dynamite (Mean girls for Boys) come out, forever ousting the Road Trip/American Pie Gen X comedy dynamic
-The Simpsons and South Park fading as Adult Swim style anti-comedy comes into focus
-George Bush reelected, solidifying millennial callousness towards most federal institutions
I guess the "rec" is just paying attention to these kinds of longer-term tidal changes in culture. It makes me feel like a wise man of the mountain when I tell 20 year olds about shit from before they were born
