Frank Miller is original. Everything he does you can certainly tell has been done by him because it always comes off as being the same. It's gritty, sexual, grimey, and the hero is always a moody fellow that talks in rasp or whisper with a penchant for gainsay and ultraviolence. That summizes EVERY Sin City story (there are around 8 or 9), Dark Knight Returns (first time Batman's seen packing heat since the thirties, totally spits in the face of Batman hating guns), 300, and now this. I'm not saying I won't see the Spirit, or anything else the guy does, but I'll always know precisely what to expect in one of his projects.
