Grant Morrison gets it
All-Star Superman previewed at Newsarama.com.
I only just got a look at this, but all you need to see is the first page to see how well Morrison not only understands the essence of Superman's backstory, but can convey it with four panels and eight words of captioning.
That page, combined with cultural osmosis, should give just about any reader enough to go on in terms of apprehending the character. No six-issue origin arcs. No interminably long and ultimately unnecessary explanations of motive and character. Just the essence, and then Superman leaping into action.
Can't wait for this.
