I think that everyone is unfair to WW fans. Superman fan always got much better.
But now with rebirth? the reception was great. here on superman boards? a tragedy with lots of complaining.
Rucka didn't said what he was going to retcon, just that he will give consistency to WW.
but BIFROST is right, we won't get a continuation to what Rucka was doing with her never again. that version is lost.
