No offense intended, but frankly I've never really understood what the big fucking deal was about Opeth. Yeah, they're great musicians and all, and I won't deny songs like Advent, April Ethereal, Serenity Painted Death, White Cluster, The Leper Affinity, etc. are all really good, but they largely just bore the hell out of me whenever I listen to them for an extended period. When listening to just about any given Opeth album, at the start I'm like "Yeah, this is pretty cool I guess", but then after about 15-20 minutes it's like "Okay, this is getting way too repetitive/dull" and I end up either tuning out or shutting it off.
Again, I respect them as musicians, and they're very good at what they do, but I honestly don't understand why so many people think they're like the best band ever.
