Dude, you may be a hard-core fan... but that is not a true or feasible statement! Maybe in your view it is that way... I mean, yes Metallica pushed metal to "the masses" if you will and they were a bit of innovators (although Exodus came before them, they were just not as lucky as Metallica), but metal would not exist without bands like Black Sabbath, Deep Purple, Judas Priest, Maiden... you get the point.
With that being said, I do like Metallica, I think that they WERE an awesome band, and maybe have the pontential to still be an awesome band... this next album will tell.
Also, to me being a hard-core fan does not mean that you should like EVERY single thing the band does, just because they are your favorites... St. Anger was the worst DISASTER in metal history... what good is there in that release? I am a major Maiden freak... but that does not mean that because they are my favs I like EVERYTHING they put out... yes, I have all the albums... but there are instances where I have only liked half an album... does that make me less of a Maiden fan? Abso-fucking-lutely NOT!
