RANT/WANK WARNING!!!
While you can't say that an artist makes objectively shitty product, given the subjective nature of taste, you can look at popular trends, you can make some conjecture about the nature of the music industry and the culture that keeps it alive, and make some philosophical points (AKA wank) about the direction that media and (consumer) culture is headed.
And it looks rather bleak. I think there's a certain status quo being made and preserved with this surge of witless hair-core bands, which is essentially that of degenerate apathy. It's more or less manufactured to piss off parents, prognsobs, and there's an almost anti-intellectual scent here; substance-free by design. However, unlike hippies, punks of the past where sincerity was tantamount to credibility, you can't make it -and- be sincere with this type of music, and it's that lack of, and discouragement of sincerity that bothers me. Like somehow the bands being "not serious" makes them somehow above criticism. The euro and prog styled metal we enjoy 'round these parts would be considered "too serious" and "not br00tal enuff" and i'm fine with that difference of opinion, but the idea that someone being serious about their artistic output is somehow a -bad- thing is just juvenile, at best. Yeah, every artist that has ever been serious about it in the history of art is lame, let me tell ya.
The appeal is obvious. Teenagers can't be arsed to care about anything beyond the superficial and disposable qualities of a given group's image and output, and to that depth they seem to paradoxically care -very much- about maintaining the image of not caring, and from a developmental standpoint that also makes some sense, since you're looking at an age peroid where everyone is scrambling to establish and maintain identity and sense of self apart from the parents.
To put things into a littl perspective, when I was of the age group that the hair-core shit appeals to, the big thing was the "WHARBLGARBL IM SO FUCKED UP AND HAVE PROBLLEEEEEEEEEEUUUUMZ RAPROCKRAPROCK!" nu-metal shit which was equally as asinine. and we all wore these:
The shit this tread is about is little more than a fairly natural consumerist evolution. It's louder, more obnoxious, more colorful and with even less of a purpose. It's a +2 flaming nu metal, and even has the same effect on the genres it takes influence from, by sucking everything good out of them, and turning into a marketable product. It's the new Limp Bizkit, and I hope it becomes as reviled as nu metal is now.
