Because they give a bad name to Metal...Because of them(and how commercial they are...) everyone who don't know **** about Metal think its only noises and screaming when there is nothing more melodic and more intelligent than some Metal bands... + Their lyrics are really dumb and the music is overall uninspired and noisy! I prefer music with intelligent lyrics than dumb lyrics like: I'll **** you, fuck the world, satan ownz, etc... They are mostly a band for ****/teens, I should say... They are posers who pretend to be satanic because **** think satan is cool...
and I see this band very oftenly in some 'best Metal band ever' poll, but its so far from being one of the best Metal band! What about Iron Maiden, Judas Priest, ***** Theater, Helloween, Queensryche, Blind Guardian, King Diamond, Accept, Loudness, Black Sabbath, Deep Purple and so much more ... ?? Now these are some of the best ever! Surely not a commercial band like Slipknot...
I also have the feeling that those who voted for Slipknot didnt heard much Metal bands...
Well, except that I don't really **** Slipknot!:1orglaugh
