I thought the movie was good but I don't Facebook bromontana..
You don't like core and more specifically clean chorus core a la Atreyu and that's fine.. I feel the same way when I listen to Led Zep, AC/DC and Def Lepard.. Hell I used to detest the 'nasal, whiney' vocals of Dickinson and Halford.
My grand dad and colleagues ask me why I'm listening to a mad man bark, grunt, growl and scream.
Bit of a conundrum really. I think you might be referring to the Hot Topic bands with their skinny jeans and streaked hair and vibgyor tattoos..
How anyone can stand them is a bit like asking how you and I can stand Erik Rutan growling for an hour while Derek Roddy blasts away.
Would I do clean chorus whiney core if I could play sold out shows, travel the world, get the myspace sluts to ride me ? You bet I would..
To each his own I say..
Sorry for the rambling rant.
