I'm enjoying this so far. And I'm invested in this story because I am hoping for a big payoff: that is, the return of the original Justice Society and maybe even the Legion of Superheroes. If this somehow brings back Impulse, that would be a fun bonus!
Two issues in, I see nothing that would foretell the return of these DC fixtures, but I'm still hopeful. In the meantime, I think Geoff Johns and Gary Frank are doing a terrific job. So far, I think Johns has been up to the task of handling the Watchmen legacy in a respectful and interesting way.
