Miller had a period of about 4 years or so where his work was awesome (DD/Batman). His art became something glorious with Sin City. However, I'd argue after that brief stint at Marvel/DC, the storytelling of Sin City/That Yellow Bastard/Return to Dark Knight was pretty average. Poor on some occasions. Probably more responsible for the comic industry 1980s move into grim'n'gritty than Alan Moore but his best stuff was 20 years ago. Little worth reading since in a storytelling sense.
