I think that I'm much more analytical now than I was when I first got into metal proper, which was about...I don't know, 84 or 85 or so when I was about 10. The real grip got me in 86 when I was 11, and back then I would pore over every lyric, gaze at the album artwork for hours and soak in the whole "mythology" of the music, for want of a better phrase. Back then, a bullet belt or mention of anything occult made it dangerous and therefore exciting to me.
So now I am that much older (and affleunt) some of the excitement has worn off in some ways. I can (by and large) indulge my passion for music much more freely with the downside that I am also less likely to spend as much time with each album.
However, that visceral rush from hearing metal, with all its pomp and over-the-top appeal has never gone. I still get giddy and smile like an utter buffoon when I see live metal. I still get excited at the prospect of seeing Motorhead for literally the umpteenth time.
Metal is always going to be my kind of music - but for the same reason that my enjoyment for Enter the Dragon has changed since I was 11 (I still enjoy it, but for different reasons now than for then), so has my enjoyment for metal. Extremity is seldom a goal in itself now, but back then I remember feeling like an utter bad-ass for making myself listen to early Napalm Death. Truth is, it was fucking garbage.
Is it less exciting then ? Who knows - it doesn't feel like it, just that I'm more jaded maybe. My understanding and appreciation has widenend significantly since my youth. Back in the thrash hey-day, I would have (and did) openly laughed at anyone in a Sabbath or Maiden T-shirt for liking "old mans" metal. Since then, not only have my tastes broadened to enjoy a portion of almost every genre and sub-genre, but also explored the older classics of the scene.
Fuck, I love metal. Seriously.
