What is the author's style in American Pastoral by Philip Roth?

Phillip Roth writes from an omnipotent viewpoint, and allows one to see inside the thinking and feelings of his characters. Using the character of Nathan Zuckerman as the "author" of the story, he distances himself from it as the creator of the story. Nathan's close relationship with the community makes the story seem more realistic and plausible. Nathan remembers Swede Levov as his hero, a celebrity of sorts, from whom he craved even the slightest acknowledgment.
