They're going to be a team?
Wonder Woman joins the fray. There's a hilarious opening scene with her exploring the modern human world. After that it's just a great action issue. I really enjoyed each part of the book even though there isn't really much time for the team to gel. If I remember correctly, after this arc the book goes back to the present day. That seems like it would be a big mistake because I'm not really sure how this team ends up coming together as a team. Right now they're just all fighting Darkseid's minions. How do they go from working together on one fight to forming a League? I'm just not seeing enough of that in these last few issues. Everyone seems to hate and/or resent everyone else. The sections w/ the cyber kid and how he's not even close to joining the fight (I hope issue 4 doesn't prove me wrong) seems to point to him still being a part of the Teen Titans for 5 years before joining the Justice League in the present. That'd make a lot of Teen Titans fans happy - I couldn't care less.
I continued to enjoy the extra material at the end of Justice League more than what's at the end of action comics, although it has been nice to get that stuff in issue form rather than have to buy the trades to get it.
