Minor GABC #2 SPOILERS below:
I totally haven't changed my mind yet about Judd Winick (not after only two issues, I haven't), but I do have to admit that I'm loving Green Arrow and Black Canary so far.
I haven't figured out what the Amazons are up to yet, but its fun watching them try to sneak Green Arrow off Paradise Island before Black Canary (whom they've invited there to train their warriors) finds out. Of course, Ollie isn't any more of a damsel in distress than Dinah is, so he makes things difficult in his fun, Green Arrowy way. Just a really fun comic.
And I like the new Amazons. I didn't like the execution of Amazons Attack, but if the end result is some tough, deadly Amazons... well, at least something good came out of it.
