John, In a way, that’s just a reversion to type. Interestingly (and FWIW), in the best Superman movies (the Fleischer animations, in my view) Superman simply fought for “truth and justice”. In the original FDR era comic books he was a “champion of the oppressed”. The “American way” came later in, I think, the 1950s. In case it’s of interest, I reviewed Superman Returns (which I liked) here for the New York Sun.
