Not even close, what killed the New 52 and it's version of Superman is the lack of planning. the lack of a clear plan, the lack of sticking to your guns and letting some characters keep their Pre-Flashpoint histories while fully rebooting others. not letting New 52 Superman have more good writers like Grant Morrison, Greg Pak and Gene Luen Yang write him instead of people like Geoff Johns and Scott Snyder. who only know how to write the Donnerverse and Post-Crisis versions of the character.
