So for the past year I've been slowly reading Urasawa's Pluto, which I've been loving! I was thinking about starting his Monster series next, but that's going out of print. The next logical choice would be 20th Century Boys, but I was curious what the board would recommend. I like science fiction and have gotten into crime/noir comics a lot (Criminal, 100 Bullets, Scalped). I've tried googling for some crime/noir manga, but haven't found much. Any ideas?
I have to admit, one reason I like Pluto is because it's only 8 volumes, not 20-30. Are there any other shorter manga series out there like that?
