When I recently decided to give the New 52 a chance, I bought a whole bunch of issues #1 after Comixology dropped the ones from the "First Wave" to 99 cents.
I dropped
Batman: The Dark Knight after that issue, and dropped
Detective Comics after issue #4. I've also dropped
Aquaman (after 4 issues);
Batwing (after #4);
Green Lantern: New Guardians (after #4);
Justice League International (after #6); and
Red Lanterns,
Superman, and
Teen Titans, all after their respective #1. I dropped
Justice League after its first issue, then decided to give it another try with issues 7 and 8 but have since returned to the original decision.
I'm definitely keeping
Action Comics,
Batgirl,
Batman,
Batman and Robin, and
Nightwing. I'm on the fence with
Batwoman,
The Flash,
Justice League Dark,
Supergirl, and
Wonder Woman. I've still only read the first issue for both
Green Lantern and
GL Corps, so can't categorize either of those titles yet. I'm thinking about giving
I, Vampire and
Earth 2 a chance, and am definitely going to try out
Batman Incorporated.
