I agree with the textbook/ history lesson feel to the narration. Part of me wondered if in creating the "bible" that tends to get set with ongoing narratives, DC didn't just ask Rucka to reprint portions as part of the narrative (ex: the out of nowhere explanation for Kryptonian naming conventions. Which, btw, made little sense to this reader. I got tuck on that panel for about five minutes trying to figure out how that applied to characters like Ursa).

It wasn't nearly as bad as it could have been as an issue, but it felt underwritten. I'd have liked more development of the points you address.
