I've liked everything LC has put out. Karmacode & Shallow Life not so much as the older stuff, but I still enjoy it. I don't hear Nu Metal much at all in Karmacode, to me it feels like a fair follow-up to Comalies with a bit more of a mainstream appeal. Hints of Nu Metal, but I personally don't see it as an all-out Nu Metal album. The change on Shallow Life baffled me, but I still like the material off that one, too.
Really, what I want is a proper Lacuna Coil headlining tour. I want to get to see them play more than the singles.
