I have a soft spot for the Justice League of America... and was grateful to @myopicaardvark for a loan of the three volume "Justice" series.
I am working my way through them. I am a slow reader but not as slow with graphic novels as I am with the written word.
I was particularly taken with Jim Krueger's prologue at the start of the first volume... where he talks about heroes and villains:
"...Gone are the days of the overwaxed mustache and maniacal laugh and human-sized logger's buzzsaw. No more does a villain raise his head from his sleep in the morning to consider what 'evil' he might do that day. No. Even if no one else sees it, the villain, in his mind, is the hero. That is where true evil resides - in the belief that his personal good is capable of navigating and speaking to the universal good.../
...Perhaps this is the difference between a hero and a villain: A villain will seek to defeat a hero for the villain's sake; a hero will seek to defeat a villain for the villain's sake. It's a fight to save the enemy at the same time that it is a fight to defeat him.../"
There is real depth in this prologue and, in fact, the novel itself... which makes it all the more enjoyable to read... along with some truly fantastic art.
