* Challengers Of The Unknown is an excellent concept but it needs to remain pared down; it resists embellishment. You can mess with the line-up, though.
* more costumes for the Batman. This is another thing where I don't quite understand the last five years of DC Comics. Because this is the kind of thing that reads totally differently if Batman's been around a few years as opposed to several.

A kid of two superheroes that is immensely powerful is a pretty good concept. But if you do 700 issues, everything gets used, and its in the use that it become a much less interesting concept.
