I have bought and read the graphic novel a couple months ago and it seems pretty good and very well written...even the artstyle itself is nice indeed.
Its not like any other superheroes comics that you read...they are more like regular people who actually called themselves customed adventurers instead of that main term superhero or crime fighter, etc...so it's set in the year 1985 where things are alittle different such as techology and all due to Dr. Manhattan's ideas...and stuff like that.
I like that one character who used to partner up with Nite Owl named Rorschach, wearing the white mask with shifting ink blots and such. he's pretty awesome.
