^Johns was a fan of the old post-Crisis continuity. He was definitely not the architect of Nu52 or the Justice League. Most of it especially the Wildstorm elements and stuff like Pandora was because of Harras and Lee. FP was Johns baby, but it wasn't really intended as a reboot, it was the equivalent of what Convergence is now, a placeholder since DC had planned to move out West in 2011. The Justice League books were a hodgepodge of influences from Jim Lee (when he was a penciller/backseat writer) , Geoff Johns and Jeff Lemire (after Lee's departure and up to Trinity War/Forever Evil) and probably also Brian Cunningham the editor of the Justice League line. The people likely responsible for reboot were probably a) WB corporate for ordering an increase in sales and b) Didio for putting the reboot on the table. 1) Lot of the New Krypton was due to management. Busiek getting fired for Robinson (before New krypton) and the hastily put together resolution where the Kryptonians were genocided by the US government after the sales on the books went to hell. 2) Many of the badly put together books were due to my opinion an exodus of editorial talent from DC during the 00s era where many of the good editors at DC were fired or left because of the toxic work environment such as Dan Raspler (fired), Pete Tomasi (went to the writing side) and Wacker (left for Marvel) as well as the firing of Denny O'Neil and replacement with Bob Schreck at the batbooks who would later be the editor for Frank Millar's screed Holy Terror. So you had people like Mike Carlin and Rachel Gluckstern running the JSA books. The former apparently being on record for disliking the JSA and the latter for not being a particularly competent editor.
