In a currently running serial that I enjoy a lot, I found the protagonist (mid-twenties and not the type to watch retroperspectives in arthouse theatres) quoting a line from the Blues Brothers (movie). I also remembered getting confused feedback when I put in a reference to The Exorcist in one of my stories. I guess it has something to do with getting older when your favourite movie references fall flat with today's readership.
Looking a bit farther, I find this to be a phenomenon that can be observed with a lot of stories. Seeing that a lot of us writers are getting closer and closer to the use-by date, we do not share the young people's frames of reference anymore. That is okay when our protagonists are old farts too, but it gets irritating when contemporary supposed high school or college kids talk like mid-level managers, only listen to The Beatles and know 1970's movies.
Don't even get me started on the shy, withdrawn, 16-year-old girls who, once they meet the thirty-something hero (successful, well off, just dumped by the bitchy ex-fiancée), learn in short order how to i) access the internet (LOL, chances are the dude can learn from the girl), ii) drive his huge pick-up, iii) fly his Cessna, iv) suck his dick (but are virgins!) and of course, v) are naturals on the shooting range, and vi) talk like news anchors. Apparently, there's a 32-year-old nymphomaniac NRA spokesperson hidden in each adolescent girl, just waiting to pop out upon contact with the right guy. And, oh yes, they like to dress like Linda Ronstadt :o)
I guess what I want to bring across is that we must be vigilant against our own mindset and frame of reference getting in the way when we write about "the youth of today". Listen to your kids or grandkids! Watch the Grammy Awards to learn what's hot today! Get drunk and watch an episode of a vampire tv series or of a sitcom with the latest teeny idol. Resist the gag reflex and note the lingo and the references.
PS: I am guilty of the same sins in some of my stories.
