I loved this book.  Rucka blew me away with this nice backstory on how the new Nightwing and Flamebird came about.  You can tell that he is co-writing the New Kryton book as well with all the little educational blurbs about Kryptonian society that really give the people depth and not just looking at them as a bunch of supermen.  I also like how he took Chris and really did something with the character.  I thought that he might have been a throw-away character in the long run but Rucka took him and hit the ground running.  Cant wait to see how Rucka and the team do next with this book.
