Currently I'm subscribed to DC's new weekly series, Countdown. It's been dubbed as "the spine of the DC Universe".
While the series is interesting, what's notable isn't necessarily in the comic itself but in the other issues DC is releasing. Last week, I've been seeing more and more "See Countdown issue #X" or "See Wonder Woman #9" for a full explanation.
I guess another possible problem is that half of the characters might end up being there just to explain various things in the other comics. So far the solid character plots involve Jimmy Olsen and Ms Marvel. The rest (i.e. Red Hood, The Trickster, the Pied Piper) seem to be busy in other books. But like everything, it's a wait-and-see before there's a final verdict.
