I'm guessing most would suggest Sandman, but I didn't enjoy the collection I read. A lot of the art work was poor and the stories not very good, in my own opinion of course.
I'm looking for darker graphic novels, that aren't very super heroish, amazing artwork, great stories, and preferably deeply involved/complicated. Longer the better, in actual length or number of series books/collections.
