On the contrary ! Opeth's death metal/blues rock dynamics are what I love about them, moving to older mellotron prog style isn't a positive move for me. I don't think they have the same edge they did a few years ago, but - they're a prog band and by that definition don't stay the same. Their highlights for me will always be Damnation/Deliverance, I never get bored of hearing those albums. I saw them in 2002 (free ticket) and they were awesome.
