Justice League Dark #0
: We get to see how Constantine, as a young man, met and fell for Zatana. It was a great story about three young people delving into magic and friendship together. What happened to the third party? Read it and find out. I thought this was one of the better origin pieces done so far.
The Fury of Firestorm: The Nuclear Men #0
: I was expecting something that dealt with Professor Martin Stein developing the Firestorm protocol, but instead, we got a consinuation of the present storyline. The funny thing is that it serves as an origin piece and turns the preceding 12 issues into a prologue or a build-up of sorts. Issue #0 establishes what looks to be the status quo for the characters and the classic Firestorm costume is finally brought in.
