Here's my problem with Dragonforce...
I always admitted that I used to love the band when they started...They were new, brought an interesting fresh thing to the power metal scene and it was great!! However, as they years went by (and my metal taste got a little broader), I was expecting their sound to change and evolve...which completely didn't happen. Their music became boring to me....repetitive and it started to bore me and piss me off...how could a band that was so good become this crappy?
And then the popularity factor came in later....It really aggravated me to see kids who were 13, 14 years old praising Dragonforce for being "The most original and different band ever", yet not even knowing who Iron Maiden was. All the power to Dragonforce cause they made their living by doing what they do, but it was a little unfair imo. I mean, look at Blind Guardian, Angra, Gamma Ray and Helloween, the bands who truly defined this genre and the scene... do they get any recognition nowadays? Not nearly as much as they deserve...
Disturbed and Dragonforce ended up doing the opposite as Dragonforce...They started with the huge popularity and then they eventually tried to make their sound different...better! And they succeeded in my opinion. If you hear the first 2 Slipknot albums, you'll notice it's totally different than the latest one, which is excellent...
I guess it is just a matter of taste, absolutely... People change and their taste changes as well... I used to like bands that nowadays I think are pure pieces of shit, and I don't think that's wrong...
