Query: Overburdened with political preaching

I found this book too top-heavy with sanctimony and political statements to be much of a read. Other authors' superheroes can fight for "truth, justice and the American way" without pushing the authors' own beliefs in one's face; unfortunately the high levels of pious preaching practiced in this book, together with the simplistic characterisation, made it very difficult to labour through to its end.
