Superheroes live in a fantasy world where there are superheroes who wear costumes. While I enjoy nods to verisimilitude and story points derived from real-world speculation, attempting a realistic approach to superheroes is inherently wrongheaded, except in certain specific situations (ironically, the best-known realistic approach to superheroes, Watchmen, works because the writer understood this). The self-conscious obsession with realism is one of the reasons live-action adaptations of comics seldom interest me. As far as I'm concerned, the best approach to live-action superheroes would be something that looked like the 60s Batman, but was written on the level of Thomas, Englehart, Busiek et al.
