Think about it like this:
If "It's Tricky" comes on I jump outta my chair like a maniac. My 20 something cousins be lookin at me like "really?".
I can't explain how impactful Run DMC was or any historical fact that will make them appreciate it. They weren't there and they can't relate. Meanwhile, all this global Hip Hop mega stardom shyt is because of Run DMC. Even the concept of wearing street clothes on stage. Doesn't sound that amazing to young people, tho.
Richard Pryor might be boring to kids. Meanwhile every comedian since is doing his shtick.
Star Wars is your favorite sci fi action movie's daddy. No way to understand the world before Star Wars cause the shyt Lucas pioneered is ubiquitous now. So when you see something modern that has been built on 30 years of people adding on to Lucas' original design, of course it's "better". Just like the latest jumbo jet is nicer than the ones built in 1980.
Those of us who recognize this fact pay homage. Plus, it's prolly gonna be a dope movie.
