I think I know what you mean. For me based on the first two issues this mini has seemed more of a Mr. Terrific vs Kobra series (guest starring the JSA & Checkmate). I guess that's what happens when the story is basically told with two distinct POVs to the exclusion of others. I love the character of Michael Holt/Mr. Terrific but Power Girl is supposed to be team leader now and she just so far has basically stood around brooding while Mr. T gets all the thought boxes. Karen/Kara is a Kryptonian from a more advanced civilization (albeit from Earth-2) and she owns/started her own successful software company. Yet it seems JSA writers rarely value her intelligence.
Having said that I think so far this has been better than the titular JSA title (the one with evil Japanese WWII undead menances, Obsidian turned into an egg and the Spectre's arch-enemy Eclipso suddenly hanging out with D-list villians). Don Kramer's pencils have rarely looked so good and I find the political angle refreshing (for once) rather than some contrived supervillian who Alan Scott or Jakeem Thunder could easily take out (but rarely do).
