To begin with, I am not necessarily against "shredding." I listen to plenty of guitarists who do solos -- including extensive ones. However, I will always prefer those playing "for the song" over a mindless yanked solo any day.
At the same time, I think some bands go too far out of their way to be simple/minimalistic. It's funny how 1970s/1980s overindulgences created a desire to hear simpler stuff, and now we're in danger of music that's too lacking in technicality and therefore kind of boring.
