I agree with you about the music of today. It lacks style and emotion. I can't relate to it either, as for grunge music, well that was the death kneel for a lot of the glam metal hair bands of the 80's, so I really do not care for grunge. I miss the 80's as well, it was a truly great decade for music.
"X-Men" is not really about mutants; it's about humanity. I think it's about the human race. We're an absolutely destructive race. It seems that we can't seem to get beyond this level of tribalism that has been around for thousands of years. Anything we fear we tend to destroy.
