I don't know, I didn't mind the newer videos actually. I wouldn't personally rush out and buy any of it, but none of it sucked either. The stuff the OP is holding up as a shining example of old-school metal actually impressed me less. While I like the Maiden song "Hangar 18" definitely isn't one of the better Megadeth songs out there (it's a low point on a good album), and Cacophony were just a plain dull shred-fest, like Dragonforce without the sense of humour.
Nothing to do with "talent" either, all the bands seem more or less equally talented and the whole concept of "talent" in music has been outmoded ever since the birth of punk in the late 70s proved that you didn't need to be a music expert to write great songs that people liked.
