I'm not a Kiss fan myself, but they didn't do anything worse than countless pop acts before them had done: Give kids something new, fun and different to get in to, and something naughty enough to shock the parents a little. The fact that they were calculated to meet that formula is beside the point. I don't care if they (or anyone else) get in the HoF (though for pre-'80s American "metal" I'd personally vote for Blue Oyster Cult), but I am glad that that they didn't go in before Alice Cooper.
And it does suck that the band won't play at the induction. I sense the massive egos of Gene Simmons and Paul "Prima Donna" Stanley at play here.
Yeah, I don't think there's much doubt about that.
