Ok I'll go first!

Definitely check out Marvel's House of M and Civil War sagas if you haven't already.
Check out Ronin by Frank Miller. Cool shit.
Check out Danger Girl by J. Scott Campbell.
Kingdom Come is a must read simply because of the fantastic Alex Ross artwork. Same thing with Marvels.
Preacher is a necessity.
Stranger in Paradise is cool. It's kinda like a comic strip you'd find in the Sunday paper, but heavier.

Now your turn!

No love for Transmetropolitan? I think vagabond would like it.

1) Meh. I have been mostly a DC fan all my life, but I read this ones. Awesome ideas, but poorly executed. Civil War 1 was actualy great but just kinda went downhill after. I have stopped reading both Marvel and Dc comics. I had to stop for a couple of monts because due to work issues and couldn't care to get back. That tells how bad I think they were getting.

2 and 3) Awesome!!!! Specially Kingdom Come (I am a DC fan after all). Life should be drawn by Alex Ross

4) very goo and funny but too preachy (no pun intended ) sometimes. Not to mention, I didn't particulaly agree with some of Enni's ideas. In fact, Ennis should have his head checked. (Read The Boys if you disagree)

5) Read a couple of issues and really didn't like it.

Now, my turn:

+The Walkind Dead (Kirkman)
Powers (Bendis - especially Vol.1)
Alias (also Bendis - especially the last arc)
Daredevil (Bendis's run)
+Superman - Secret Identity (my 2nd favorite Superman Story)
All-Star Superman
DMZ (Brian Wood)
Jack of Fables (Fables spinoff)
Criminal (Brubaker)
Sleeper (both volumes - Brubaker)
+Batman - The Dark Knight Returns (Miller - I don't recommend The Dark Knight Strikes Again - I found it horrible)
+Daredevil - Born Again (Miller)
Gotham Central (Rucka/Brubaker) - Gotham through the life of cops instead of Batman. Awesome stories.

There's a lot more but this should keep you busy for a while.

PS - The ones with + are the ones I think you should go first.

I have been wanting to get this, and the V for Vendetta graphic novel. It's supposed to be so much better than the movie. (which I liked anyway)

Yes. The comic is much better than the movie. Moore is the author of both, actually.

What is a good Batman one? I hear that Batman has had some pretty classy books. I might check out V for vendetta if it's the same writer as Watchmen.

The definitive Batman story is Frank Miller's "The Dark Knight Returns". That is your first priority in reading.

The second most important is Batman: Year One, again by Frank Miller. You'll notice this book was a huge inspiration for Batman Begins, but is ten times better.

Other excellent books are:

Batman: Hush Vol. 1 and 2
Batman: Knightfall
Batman: Gothic
Batman: A Death in the Family
Batman: Black and White Vol. 1
Batman: The Long Halloween
Batman: Dark Victory
Batman: Arkham Asylum
Batman: The Killing Joke

Get to reading!

thanks for the recomendations. I will take that list to Barnes and Noble.

Yeah... I know a lot of people that don't like Comic Books...

but do like Alan Moore's comic books.

For the person who has an open mind, but doesn't like many comics...

Alan Moore and Neil Gaimen are basically the guys to get.

Frank Miller... is a bit of a beartrap. He has some REALLY AWESOME stuff... but he also puts out some of the worst garbage out there... so his stuff... be wary unless it's one of the big ones.

Watchman is a great but very rare comic. I'm just re-reading it myself.

V for Vendetta is also good (see the movie too). Also you might be interested in the classic Sandman series by Neil Gaiman.
