The author had a great idea, but he cherry-picked the available info about Superman and the writers to get the book to make sense. For example, Superman was originally written as a metaphor for Jews during WW2. Two Jewish guys, right at the end of WW2, write a story of a man that has to leave his homeworld b/c it's destroyed... etc, etc.I'm not critiscizing this book b/c it has a religious message. I'm critiscizing it b/c the author clearly left out clear facts that work against his arguement. Otherwise, I disagree with anybody that says it is "just a comic." Superman has often reflected the current values and attitudes of a large swath of America.
