I really, really wanted the "New 52" Aquaman to be similar to the Batman: The Brave and the Bold Aquaman, but apparently, people are not ready for awesomeness on that scale. That being said, the current title is enjoyable.
I am enjoying Green Lantern, but then, I'm a GL, specifically, a Hal fan. I love Hal even with (because of, perhaps) his faults. Love the Sinestro/Hal team-up.
I got caught up on Stormwatch this weekend and enjoyed it. I never read any of the Wildstorm stuff, but once I finish other series I started in TPB such as Sandman and Starman (both of which, I started collecting over 10 years ago!). Then, I might pick up The Authority and my opinion might change, but as far as being new to all of these characters (J'onn being the exception), I am really enjoying it.
As far as the oft-discussed Action Comics, I felt like issue #3 was rushed. I really like Morrison's comics and I realize that his style often leaves a lot off-panel, but this issue shifted from one scene to another too quickly, with no transitions or segues. It also seems derivative of Secret Origins. I'm not arguing that Morrison ripped Johns off, or anything, but they both hit upon some of the same notes, such as Metallo.
