Another thought to throw into the mix...
For those of us who were born in the 70s and grew up in the 80s... have you ever seen a film, or read a book of which you've heard a great deal but didn't get around to doing until your 30s?
For example I didn't read 1984 until 5 years ago. I can understand why it's a great book but sadly it's been so plagiarised, and every idea or concept has been taken and expanded on in so many other derivative works that I didn't especially enjoy it. I don't regret reading it and Orwell writes a good book... however I wonder if it's the same for 80s culture for people born in the late 80s/90s. Do they look at the 80s stuff we wax lyrical about and think it's a bit basic, they've seen it before and it's nothing really impressive?
Catcher in the Rye for me.....read it in my 30s. Although not a 80s book, it was a cultural icon where I grew up.
