the movie market has changed in the meantime, but why is there no similar talent ... I'm suggesting some of newer generation are not there by merit.
It's unclear, are you just talking black talent or talent in general?
I'm sure there was plenty of poor talent around
(of any colour) 26 years ago as well and no one remembers them now, its easy to cherry pick a few actors that were and are still great.
It's the same with music, you hear generation after generation talk about all the great music
"in their day", at the same time there was a fair amount of terrible music
"in their day" but they won't remember that.
