Frank Miller's
RONIN.

I loved the first issue, some of the best pages of Frank Miller's career. Great visual storytelling, and a wild mix of medeival Japanese ninjas and post-Apocalyptic New York City, with a futuristic military complex built on the ruins. Although all is not what it seems until the final issue.
I was a bit put off by how the art increasingly resembled Moebius in issues 2-6, but the story has grown on me over the years.
I think it suffered greatly in popularity because it took Miller FOREVER to produce those issues, and it didn't come out on a regular basis, that many got tired of waiting for. It gained revived interest after Miller's later DARK KNIGHT RETURNS, YEAR ONE and DAREDEVIL runs were released in collected trades.
