I'm hoping it's a grower - they're a bit of a sacred cow, British Black Metal being the weird little runt it is, and although I've been expecting them to make something subpar for several albums now, they've managed to make each album worthy of existence in its own right.
I would say that some of the songwriting spark that made killer tunes like Do Not Speak and To Err Is Human - To Dream Is Futile so amazing is gone, however. And that's a real shame. Having clean-sung choruses that all sound the same is not a good replacement.
