I think we're getting close to the point where retro may be the only way to go for superhero films. I mean, technology is getting to the point where maintaining a secret identity will soon be impossible, especially with innovations like this laser sensor that can detect trace amounts of any substance and even read through clothing from 50 meters away. Not to mention things like ubiquitous cameras that can track you just about anywhere, facial recognition sensors that can identify you from just a small part of your face, etc. Not to mention that the way journalism is changing makes it hard to tell stories about the Daily Planet or Daily Bugle anymore. And I've been saying for years that the Batsignal is an obsolete notion; by now Commissioner Gordon should be doing something like sending Batman a tweet.
