I tend to view the Superman from after The Crisis On Infinite Earths to the beginning of Flashpoint as one solid iteration of the hero that lasted 25 consecutive years (1986 - 2011).
I'm slowly coming around on the idea that there is a definite difference between the Superman of the late 80s/90s and the Superman of the 00s/early 10s, and that they should be considered 2 distinct iterations of Clark.
So, what are the big differences?
Where/when is the demarcation line?
Differences in abilities, attitudes, origins, appearance, etc?
And which one of the two was your preferred take?
