I think Nightmare's great, a solid 7.5/10. As I said in the thread over on the DT-side: it's miles better than their self-titled, and while not as consistent as City of Evil, the highs surpass it (I know that part will be controversial).
God Hates Us, Save Me, Fiction, Danger Line, and Victim are my favorites, and I really enjoy the others as well (though if any gets skipped, it's Tonight The World Dies).
