Good point. Still, a powering down I think was justified after the Silver Age, if not necessarily to the point that John Byrne did. Superman in general is a hard character to write faithfully to his modern characterization while still being interesting. In terms of characterization, the modern Superman is about as alien as his physiology: Where most characters, superheroes or otherwise, like Batman are based on their character depth, modern Superman is actually based on his lack thereof: He's intentionally designed to be perfect and flawless to be a moral exemplar. This causes him to be a simple character, which coupled with his immense power makes it hard to really challenge him in a physical, intellectual, or moral way. Especially today, it is hard to relate to his simplistic views on morality and moral issues, because "doing the right thing" is not as simple as it sounds in this day and age when there are so many thought processes, moral and ethical systems, and philosophic viewpoints on what the aforementioned "right thing" is.
Thoughts on this analysis of Superman in our day and age?
