I am an avid reader of The Walking Dead, Outcast, Sons of Anarchy, and Captain America, and I have Agents of S.H.I.E.L.D. #1 waiting for me next time I go to the comic store.

 

I did read Naruto before that ended. I tend to follow the comic summaries online. Loved Astonishing X-Men (penned by Joss Whedon)

 

Mobile Suit Gundam: The Origin, along with the Walking Dead (catching up), and (IDW) Transformers.

 

Back when I had time to read them, Preacher was my favorite. Garth Ennis is incredible

 

I started Batman Beyond 2.0. Its really good.

 

Anything Batman is good. I also enjoyed reading Watchmen. I started reading Ghostbusters and Ninja Turtles since I'm a huge fan of both (they did a crossover series as well!). Also got into X-Files as they did a continuation of the series but I didn't enjoy it as much I thought.

 

Saga is pretty fantastic. You should also check out Vaughn's other series, Y The Last Man. I also like Fatale by Ed Brubaker. It's sort of a noir comic. One under-the-radar book not a lot of people talk about is Chew. It's a pretty bonkers book, but I really enjoy it. The Walking Dead comic is arguably better than the TV show.

If you are wanting actual graphic novels as stand alones you can't really go wrong with any of the classics by guys like Frank Miller or Alan Moore. Launchpad mentioned Watchmen, that's considered "the" graphic novel in a lot of people's minds. I'm also personally a big fan of Neil Gaimann, even his novels.

 

Preacher is a must read. Sandman had it's moments. I am also in the middle of Fables, I am enjoying it as well.

 

Frank Miller's "The Dark Night Returns", or any of his Daredevil stuff. David Mack's Kabuki.
