I've never understood the dislike for Weakness. It may be the weakest song from Damnation, but I think it ends the album on a dark, haunting note. It's a mood piece, through and through. And I love the last line: "I'm not afraid of what you have just done, but of what you've just become." The words themselves are chilling, as is Mikael's delivery.
There are FAR worse songs in existence; including Opeth songs. And I'm voting against Ozzy solely on principle, because everything Opeth does makes Ozzy look like a whining kid on a playground who throws a tantrum because he wants to go down the slide but can't because the other kids won't give him a chance.
I suck at metaphors.
