My issue with them isn't that they're old. And it's not even so much that they changed after Justice. It's what they changed into, how they changed into it, and who they allowed to captain the ship while they made the change.
They went from a band who shit on the mainstream, only to go mainstream, a band who shit on music videos only to make a couple dozen of them, and a band who shit on glam bands like Bon Jovi and Motley Crue, only to hire their fucking producer (Bob Rock) to lead them through the sellout process.
I don't care that they're old. I'm old. And I don't care that they changed. It's that they changed into something that absolutely betrayed everything they claimed to be, along with the fans who believed those claims.
And it probably never would have happened had Cliff not been killed.
