Totally see what Brevoort is saying from a story telling stand point. The marriage had 15 years of a lot of good writers trying with the status quo but Superman as a character (apart from Elseworlds) was very disappointing and failed on many levels to be interesting. He felt very boxed in, bland and conservative and worse even more whiny and he was supposed to be "happily married" . What irony.
DC starts fresh and goes back to his roots with a more modern sensibility and with it comes possibilities.
