It's a matter of taste, but featuring Darkhawk and Quasar is not a way to endear a book to me.  That being said, I don't think it's entirely because of their presence, but this tie-in has definitely been the weakest point of an otherwise wonderful book.  Coming to its defense, I would be likely to believe that the SI tie-in was forced on the book, and that left me all the more surprised that they not only brought back Worldmind so soon, but during this arc.  We all knew he would be back, but I figured it would be sometime after the SI issues.  I was also somewhat surprised to see the Nova Corps resurrected, but there's your bridge out of this arc, I guess.  Anyway, although there was nothing really wrong with the writing or art, I found this arc to be rather inconsequential and weak.  Hopefully Worldmind and Nova will share a body again soon, and we can get back to some Odd Couple Human Rocket action.
