What's Good

Here is a list of comics that I'm reading right now all of which I vouch for if you want to try it:

Superheroes!

Detective Comics - Paul Dini, the guy that wrote the Batman cartoon in the 90s, writes this and it's AWESOME. It's just Batman being smart and solving mysteries. And punching.
Runaways - Awesome series about little kids who find out their parents are supervillains. Joss Whedon just took over writing it and it's only gonna get better.
Irredeemable Ant-Man
Green Lantern Corps
Omega Flight - This just started. It's about Canada starting a superhero team again. We'll see.
Superman
The Spirit - This genius named Darwyn Cooke is reinvigorating Will Eisner's old comic strip hero. It takes place now and the Spirit is fighting terrorists and stuff and it's really cool.
X-Men - This series is pretty good but a little too crazy. Something big is supposed to happen in a few issues so I'll stick it out and see.
Shazam and the Monster Society of Evil - How could you not read something with that title?
Fallen Son: The Death of Captain America
The Initiative - This is a Marvel series about each state in the Union having to have it's own superhero team. I'm really only reading it to see who South Dakota gets (c'mon, Sleepwalker!).
Newuniversal
Punisher War Journal

Stuff that is really awesome but only comes out once every solstice:

Right now there are a lot of great creators making a lot of stuff, and sometimes things get really really delayed. The following are all really good but don't come out often enough. They all have really great art, which probably leads to the delays. They're all worth checking out and will be easy for you to catch up on as they only come out a few times a year (seriously).

All-Star Batman and Robin - It's Frank Miller writing Batman! And Jim Lee drawing it! Sounds awesome, right? Well, the last issue came out in AUGUST.
All-Star Superman - This comes out every few months and is AMAZING. Grant Morrison writes and Frank Quitely draws and it's pretty much the best Superman stories ever done.
Astonishing X-Men
Action Comics
Batman - Okay, so this does come out every month, but the main story being done by Morrison and Kubert keeps getting delayed so they fill it in with lesser (but still good) stories.

Ed Brubaker!
One of my favorite writers.

Uncanny X-Men
Daredevil
Captain America - He was assassinated in the last issue, so who knows what happens next.
Criminal

Garth Ennis!
A crazy Irishman who writes really good hardcore violent stuff.

Chronicles of Wormwood
Punisher - It's Punisher in the real world. There's no supervillains, just Punisher killing drug dealers and slavers and stuff. One time he pulled this dude's guts out and strung them up in a tree while he was still alive! Good stuff.
Barracuda

And, the Walking Dead by Robert Kirkman is totally radical.

That's it.
