It is interesting to note that DC Universe 0, which flowed about as well as a given issue of Marvel Previews, was ten times the comic book that Countdown was, and received by DC fans at about the same rate.

The rousing success of DC Universe 0 makes me think that there is a sort of blueprint you can follow to see what the generalized modern superhero fans will enjoy. They appear to want at least one of the following two things:

1. The comic to be good

or

2. The comic to "matter."

52 (as a whole) was good, DC Universe 0 "matters." Countdown gave the fans neither.
