There will always be people jumping on the bandwagon, I think that I've never noticed it before, I was quite heavily into nu-metal at first, but I grew bored and disillusioned with it when there was nothing new coming out, I'm not a person who knows little about the genre, I own the first 4 korn albums, ones by disturbed, mudvayne, deftones and many others, so I actually have taken the time to listen, I'm not just judging the bands from looks or the odd bad track alone.
Korn had some originality, as did a few of the first nu metal bands, but the genre rapidly spiralled out of control and it seems that every new band doesnt have anything new to say
I feel that from a guitarist's point of view, a person who has spent many years practising and performing, to see these people, some of whom have talent but dont use it, playing generic, boring, unoriginal music, there isnt enough musical variety or dynamism.
I listen to lots of genres other than metal, and dont have such a problem, I find softer rock to be original and captivating, there is still new music coming out in all kinds of areas, just not metal, I'm glad this has sparked off such a lively debate, one strong enough to get me hate emailed!
guns dont kill people, people kill people, and monkeys do too (if they've got a gun)
