For recent non-superhero comics check out:
The Walking Dead
DMZ (Even my friends who hate comics like this one, check it out for sure)
Y the last Man (the series just finished a few months back, so you can sit down and read the whole thing)
As far as Superhero comics, all I’m really reading is random Batman trades atm, so I can’t really help you out there. I hear the newer Punisher is badassed though, so pick some of his recent stuff up if you have the loot.
I’m not sure how much you’ve read, but I’m assuming you’ve read a majority of the classics (Sandman, Preacher, DK ect ect.) If not you might as well say fuck it to the current stuff and read the essentials first.
