The symbolic interpretations of Batman whose "supreme force of will" awes people with superpowers are the ones I can't see. Other, less grandiose (as in megalomanical delusions) readings seem far more appropriate. My comments were aimed directly at Anders', not elsewhere.
But since it comes up, I don't think Moby Dick permits much reading other than a symbolic one. That may be why some people bitterly hate being forced to read it, or even boast of never having read it, like Spider Robinson if I remember correctly.
