Too Short
Well, I've read both issues so far. They were okay, but they seemed like they were really short. It seems as though nothing at all has happened yet. Basically, It reviewed what's going on in the JLA/JSA crossover, the "Lightning Saga". Darkseid has a plan... again. And it's introduced Jason Todd as the new "Red Hood", as well as the photographer Jimmy Olsen, and has revealed that Mary Marvel no longer has any powers. Oh, and Duela Dent has been killed by one of the "monitors".
It's not as great as 52 so far. 52 had a great story all the way through, as well as a mind blowing ending. It will be hard for Countdown to live up to what we all expect after 52, but I hope that it at least gets a little better than it is.
