Trinity is in the Superman Editorial office, partially because Superman/Wonder Woman was there, although it is just as much replacing Batman/Superman as well.
But Justice League is a team book, it's not really Super Family. It could just as easily really focus on Mera (and by extension Arthur) as the last two issues have, or focus on the Lanterns, etc., etc.
You're right about the rest. >>93982215>>93982256
Superman was also selling like 500K copies of Jimmy Olson and Lois Lane, not to mention Adventures or Superboy, Supergirl, and his own books.
They could easily have a mini, either in universe, or something like The Coming of the Supermen, or American Alien.>>93982257
I haven't read past the first arc, but the dynamic with Steel, Natasha and other aspects can make it interesting. I just don't think the Lena story was really that interesting or novel - it read like bad fan fiction - and the art was just awful. It just needs a better writer.
