The only Opeth albums I particularly enjoyed were the first two (especially Morningrise) and Damnation (I have no idea why I like that one so much). Not that I have any other problems with their other stuff, I just find them a bit repetitive (as in, song starts off ballad like, which then surprise attacks you with 5 minutes of pure growling, with another few minutes of ballad after that, to make sure their songs are at least 10 minutes). Then again, i'm more of a thrasher. Opeth's pretty cool though. I still need to check out their new album.
