When you stop to think about it, superheroes must have bad days too. And man, are they having a bad day in this book. I wasn't all that familiar with the characters, although anyone who's read comic books will have a passing familiarity with them -- Green Arrow, the Flash, Superman, etc. But what's great about Meltzer's story is that you really don't HAVE to know the characters in order to feel for what they are going through. And what was even more interesting to me is that the book acknowledged that prior actions taken by the superheroes, with the best of intentions, may have gone really wrong and caused the problems they were facing today.
In short, I really enjoyed this graphic novel. It was an interesting story, very well-drawn, and extremely compelling. (Plus, for those of you who like closure, it has a clear beginning and an end. :)
