As mentioned by a previous reviewer, this series is written by Keith Giffen and JM DeMatteis who did the 80's campy series JUSTICE LEAGUE. These two comedic masters, with the amazingly humorous pencils of Kevin Maguire, renovated the JLA in the 80s and added something that comics needed at that time: humor. Sometime between 1986 and 1987, comics became overwhelmingly grim. Wolverine was staking his claim as a hardened good guy. Batman became known as the Dark Knight properly thanks to Frank Miller. The X-Men became more about their inabilities and personality weaknesses than about their mutant powers. Comics were becoming less fun and more "realistic" incorporating the all-heroes-have-miserable-life-issues motif into issue after issue. So the trio of Giffen, DeMatteis, and Maguire gave popular comics a slap in the face and fans responded by slapping their knees (while laughing, of course).
So now almost 20 years later, the "Unholy Trio" prove that they still have it. Back in '87, they took unloved characters like Booster Gold, Blue Beetle, Mister Miracle, and Guy Gardner (to name a few) and made them lovable fan favorites. This time around, Booster and Blue Beetle are still around, but added to the mix of heroes are Mary Marvel, Elongated Man (and wife Sue), Fire, and Captain Atom.
I was initially afraid that the writers would not be able to keep their flavor fresh with humor. I was wrong. Giffen and DeMatteis are still funny and still love the characters they write. This series is about the characters, not mainly about what the characters' actions. The characters are well-written and lovable, and so what they do is just a product of their personalities with humorous and clever results.
I was also initially afraid that the artist (Maguire) might have lost his ability to draw the greatest facial expressions in comics. He too still has it. In fact, he is a much better artist now. Maguire's story-telling has improved, and with that mixed with his classic ability to contort a character's face really enhances the characters. He's able to enhance a character's dialogue by their expression that so effectively conveys their emotional state and temperament. That right there really makes this book worth reading and admiring over and over.
Heck, DC even got the under-rated letterer Bob Lappan in to work the whole series. If you've never really considered how a letterer can add to story-telling, then I highly suggest you give this book a gander and examine Lappan's talent for effectively enhancing a story with properly timed "tiny" letters (which I think he popularized back in the day) whenever a hero was embarassingly muttering to himself. Lappan is also able to emphasize key words without beating us readers over the head. It's really a talent to letter, or so he quietly shows us.
Anyway, pick this book up. If you've never experienced a Giffen/DeMatteis/Maguire book, then you need to start. They will also be working on "The New Defenders" which comes out this summer. That too looks more than promising.
Humor in comics isn't for everyone, but if you pick this book up, then you'll more than likely find out that when humor is done right (like this), it's for basically everyone.
