This review seems to imply that the story is written as if Barry has actually been gone for twenty-plus years in DCU continuity:
  • Barry is not seeking salvation or forgiveness for his trespasses, he is a man trying to find his place in a world that has become virtually unrecognizable.

    As Keystone City gets ready to honor the return of Barry Allen with parades and other such fanfare we are presented with a man who is quite simply lost. It wasn’t until I saw our modern world of cell phones, text messaging and other Web based trappings through Barry’s eyes that I realized how much our lives have changed over the past quarter century. The irony of a man who can travel faster than light grappling with the concept of instant messaging is just one of the subtle nuances Johns carries throughout this title.


Is that really the back story? Because if it is that doesn't make a lot of sense in a continuity where Superman and Batman are supposed to be in their late 30s.
