I read graphic novels, I don't follow comics.
Sometimes I pick up trades, right as they come out, so I suppose that could be counted as following a comic storyline... but I prefer to have my story all-in-one, or segmented into large volumes.
Single comics just annoy me now. You get right into it... and it ends.
Most graphic novels and trades are set up to tell a whole story, or at least a whole segment to a story, and therefore you have a proper build-up/crisis/denoument set-up, which I really like.
So, what I've read recently;
Walking Dead volumes 1, 2, 3
Sin City
Sin City: Booze, Broads and Bullets
Sin City: A Dame to Kill For
Sin City: Family Values
Batman: The Dark Knight Returns
Batman: The Dark Knight Strikes Again
(you can see I'm a Miller fan
)
The Gift (total crap, don't bother with it)
