"New Krypton" from Superman: World of New Krypton #2 (DC, 2009) by James Robinson, Greg Rucka and Pete Woods
While we can (rightly) criticize Superman's absence from Earth for a year while other characters took over his books (Mon-El, Nightwing & Flamebird, etc.), I DID like the New Krypton storyline. Kal-El as a member of the Kryptonian military/security forces, serving under Zod no less, was a great hook, and besides, those other heroes on Earth got some very engaging stories they would not otherwise have been allowed to have (I doubt they could have carried their own books for a year). I also dig how all the Kryptonian styles we've seen over the years are represented in New K's caste structure. It's what happened with Superman afterwards that creates bitterness for the year of WNK, because Superman ONCE AGAIN left Metropolis to walk across the United States. Not what was required after such a long story arc away.
