This book suffers the same fate as so many of the new DCU 52. It's average and a tad bit boring.
What can I say? Jurgens give us a typical first issue for a team of superheroes. There's no shocking Thuderbolts #1 ending that ropes you in for issue #2. There's a lot of characters in the book which all are not really developed yet - hopefully they will be in the near future. The art is solid. Oh yeah, Batman is in it for some reason.
All in all - It should be called Justic League Average - 3/5.
