agree with everyone that old IF, AE, DT, etc is rulage, and this new stuff does nothing for me, but the way i see it is all these bands change, and that's just something that happens. In Flames get the brunt of the hate because they got very popular.
When I look back to my favorite metal bands in 1997, the only band that hasn't let me down is Meshuggah. So that's a rare occurrence when it happens that a band suits your tastes as you get older for a period of over 10 years.
In Flames, Arch Enemy, Opeth, hell, even Nevermore, all changed over a decade into something that didn't appeal to me that much anymore, and i don't really have animosity towards them, I still love the old shit as much as I loved it back then.
