I think, to be fair that bands like Swallow the Sun would have once sat very well next to Katatonia but nowadays Katatonia is a very different sort of music yet still seems to trail around with a doom metal following of support bands when they almost sound like Muse in places (only a little).
I don't think Katatonia sounded right but they are not really the Katatonia I loved that was Tonights Decision and LFDGD anymore, they have evolved and as such I don't see the new members as a bad thing. But for the onlder stuff, I agree they have to let it go a bit now because they dont do that stuff.
