This seems absolutely unnecessary.
I completely agree. I would go as far as to say that, in my eyes, the 'New 52' as a whole has only worked out positively for a few characters.
I would also agree with people's sentiments that they should have released #0's BEFORE they started wheeling out their #1's if only to orient us to what had and what hadn't happened in this 'new' universe. Almost a year in and I'm still not sure what is canon, what isn't, who exists, who is dead, who isn't. It's maddening.
Oh well. I guess I'll just keep reading Animal Man and nothing else.
