I just finished reading The Authority: Revolution - Book 2, which is the follow-up to The Authority: Revolution - Book 1. This two parter, written by Ed Brubaker with pencils by Dustin Nguyen, tells the story of the Authority deciding to make the world better by taking over the United States, then consequently screwing up royally and eventually trying to recover.
The Authority is a hard book to write. Warren Ellis in his original run basically tried to make a closed series and had a very simple theme of "big action," topping out with the "killing the planet-deity" arc. Millar had a so-so mix; his first arc started with the promising premise of toppling violent regimes and then became a traditional superfolks versus superfolks story. His Earth Inferno story successfully competed in the "big action" theme by pitting the Authority against the Earth. The concept of Under New Management -- the powers-that-be attempting to replace the Authority -- was reasonably good, too -- and a nice switch from the "big action" idea.
Robbie Morrison put me off the Authority after this, with what unfortunately felt like retreads of the earlier "big action" concepts and fairly flat use of the "ultimate badasses" personality tics of the Authority.
I'm a big Brubaker fan, though. When I saw his name on an Authority book, I gave it another chance. I like how he took the "overthrowing a government" idea and ran with it -- with the natural consequence that the Wildstorm universe changed even more. By the end of the book, it's really, definitely not our world with superheroes tacked on, and I appreciate that. I also think Brubaker did a solid job with giving actual personalities to the Authority, letting them show doubt and many other emotions that aren't "sarcastic self confidence."
I don't know if I believe in a successful follow up to this series, but this was a good, just-different-enough take on the Authority. I'd recommend it.
