Normally I don't agree with Chedsey's bizarre reviews... or his relentless Opeth-bashing... but I have to agree with this review. I found "Damnation" to be quite unremarkable and underwhelming.
I found this part of his review to be extremely hilarious:
The eight songs of Damnation are all quite easy on the ears and provide suitable background music if you are reading a novel or grooming your cat. In fact, you may find yourself petting and tending to your cat longer than normal since this album will lull you quite so. Your cat may appreciate multiple listens of this album.
