So why is it that this comic is as good as it is despite a trite and cliche premise? Simply because Geoff Johns understands Superman. And while this kind of story is Science Fiction 101, putting Superman into this kind of situation - where Superman is playing the skeptic against blind idealism - is a novel idea that works well within the context of the story. Clark is a reporter by trade, after all, and a big part of Truth, Justice and The American Way is about seeking the Truth and dealing with it, no matter how ugly and uncomfortable it is.
The artwork is comparable to the story in that it is by-the-book by the standards of the team involved but that standard is a high one and the final product is enjoyable. John Romita Jr. isn't as famous for splash pages or background work as some artists but his work here is eye-catching and memorable. The inks of Klaus Janson and Laura Martin's color further enhance things.
