Neil Gaiman provides a solid essay on the topic of "The Myth of Superman" as a sidebar for a feature on Singer's forthcoming film in this month's Wired Magazine. The shared credit with "a senior editor at Wired" suggests to me that this is actually a phone interview edited and reformatted into essay shape, but it's still worth reading. Gaiman hits the high notes, and probably doesn't say anything about Superman that comics cognoscenti won't have heard a million times before, but it's all worth repeating in front of the unconverted, and I'm sure some of them must be reading Wired.
