Adult/High School - Fingeroth offers a lucid and accessible social critique of the mainstream comics' preternatural characters as well as reasoning why and how the public welcomes such stories. Although he rightfully reaches back to earlier literary uses and developments of heroic character types, these discussions don't demand strong academic knowledge of world cultures, nor do his analyses of superhero motives require readers to be grounded in theoretical psychology.
Instead, this is an engaging discussion that may turn some readers into literary sleuths and deeper thinkers, simply because the writing is so solid and the presentation so balanced. Even those who aren't fans of Spider-Man or Batman will be able to understand the relevance of considering how fiction and culture interact with one another.
An excellent resource for both research and pleasure reading.
