Last week was about the fifth time I've heard that there is a mandate at Warner Bros. regarding any of the DC superhero films in development, and it's very simple and direct and to the point.
It would seem like a crazy rule to set for an entire series of films. How can you know what the tone is for every story you'll be telling in a series before you've even started telling it? The thing is, DC has taken a few stabs at establishing this larger universe on film, and they've gotten smacked down for everything that hasn't had Batman in it. "Man Of Steel" made money, and I'm certainly not the only person to like the film. I may be one of its more ardent defenders, but I'm not alone. I think you'd have a far harder time finding someone to defend "Green Lantern," the studio's other big attempt at launching one of the core Justice League characters with a film franchise of his own.
