Thought that was the thing people loved about Rebirth. If that didn’t sell you on it, that’s Tomasi and Jurgens’ fault. Rebirth was pretty much the Clark & Jon show with Clark training Jon.
Well considering Johns, Jurgens, and Tomasi eliminated any suffering or screwups from Superman by restoring more or less the Byrne Superman who had everything delivered to him on a platter, a screw up of that magnitude works well to show how flawed Clark & Lois are.
