True to my word, I read the new Justice League of America #1 last night. (Minor spoilers as usual.)
In a word: Hrrrrm.
It seems that Geoff Johns is spinning our Space Cop into mysterious and deadly territory. His encounter with Byth (or I should say "Byth") is something which either previous version of Katar Hol would never do. He'd bash the perp's head in with a mace, sure, but the combination of the detached, clinically cold attitude and a seeming lack of concern for the law are whole cloth additions to his personality -- both pre-New 52 and in the present. This goes beyond Space Cop. We're even moving past Space Dirty Harry Callahan (remember that in Magnum Force, Callahan said that the law may not be perfect but it's the one they have and until there's a better way, he will enforce the law) and into new territory here.
How does this resolve with Savage Hawkman? Who knows? Considering that the solo book ends in 3 issues, I'm sure a lot of readers are asking "Who cares?" instead.
It's clear to me that Johns is making Hawkman as much a mystery as anything else in this book. I may be more prone but he hooked me in this issue.
Now it's time to deliver on the potential and knock this book (and Hawkman's depcition therein) out of the park.
