For most of my youth there was only really 2000ad, in Britain. Luckily it was brilliant.
These days I'm still no great fan of superheroes, with their enormously convoluted shared worlds, and tend to read more self-contained series from the likes of Vertigo and Image. I'm currently enjoying Lazarus, Saga, Fables and Northlanders, for instance. I only read collections/graphic novels - no monthly comics. Occasional manga, although it's hard to find the ones I like.
