I just recently let myself buy comics again. None of these are super hero comics per se, but all are really great.
Northlanders, there's two trades out I think, written by Brian Wood (Demo and DMZ), each trade collects a single contained story about vikings in one way or another. It's really really good. The art is beautiful and the writing is super great. The first trade is probably one of my favorites ever.
The Programme, two trades out as well I believe. Don't remember the author or artist. I've only read the first trade. It's set in the modern day and is about weird cold war era experiments to create super mutant fighters. Kind of weird, but I enjoyed it a lot.
Losers, it's done now. From a few years ago. There's like 5 books I think? A black ops team is killed off by the government but, whoops!, they survive and spend the rest of the series trying to exact justice. Not smart exactly, but a lot of fun. The writing is quick and clever, and when the main artist, Jock, is drawing the art is really amazing. Oh and they're turning it into a movie, but I have no idea if it looks any good.
