Pretty much like the title says.
I was deeply invested in the New Krypton Arc. I followed all the books, even the Supergirl titles which I don't normally read.
From
The Coming of Atlas
Brainiac
New Krypton
SupermanL Mon-El
Supergirl
Codename: Patriot
Nightwing and Flamebird
Last Stand of New Krypton
and finally
War of the Supermen
And the result of my investment in this 2 year long arc was a BIG DUMB ENDING and a reset of the status quo.
After bringing back so many Silver and Bronze age themes and characters; that were woven in to a clever story. How could things go so wrong right as the series prepared to cross the finish line? Was it a change of writers and thereby a change of vision?
Geoff Johns had been threading Superman's Silver Age mythos back in to his Post-COIE canon prior to Infinite Crisis. Johns left Superman around 2009/2010 to work on GL and the big Blackest Night + Brightest Day storyline. James Robinson picked up the threads and was put in charge of Superman New Krypton vol 3-4, Last Stand of New Krypton, War of the Supermen and Mon-El's story. Robinson was also writing the JLA at the time.
Or was it behind the scenes editorial mandates that sabotaged Superman's New Krypton arc?
