This title really makes DC seem almost like they, as a company, have institutional ADD. They keep jumping from thing to thing.
"Let's make another JL title and call it JLA! They can be frenemies with the JL!"
"Let's have the various JLs fight each other and be REAL enemies!"
"Let's have JLA become JLC!"
"No! Let's have JLC become JLU!"
They can't seem to stick with anything for more than a couple of months. At this point, they should probably get rid of the concept of the ongoing series, and just put out 52 4-6 issue miniseries and just keep cycling them. For bonus points, have each mini be set in a different universe, so they can do 52 cycles, one per universe.
I know it sounds crazy at first but that is 90% of the way to what DC is already doing, just not formally.
