I wasn't overwhelmed by the first issue. I like the idea, I like the character mix, but I'm so sick of this "decompressed storyline" business. This one I'll "trade-wait" and decide if I want to look at it then.
It was the same reason that Team 7 was formed "5 years ago" which Amanda Waller was also a part of.
Are they calling them the Justice League? If so, that still makes sense as it sounds better than Meta Watchdog Squad. Just like Department of Defense sounds better than Department of War.
The first title was Justice League, this is Justice League of America. I don't know how much of a deliberate commentary it is on our times that the Justice League was formed to defend the world from Darkseid should he ever show up again and the Justice League of America was formed to protect the world from the possible threat of Superman and Wonder Woman's baby... should they ever have one.
