I will never understand the reasoning behind Frank Miller ever wanting to direct his own superhero movie. It’s not that he’s directing a movie, either, it’s that he’s directing a movie in the style of Robert Rodriguez’s fast and cheap process where he merely places his cast in front of a green screen for ninety percent of his film. And we must endure a hundred minute crime thriller with people that stumble around a CGI world. Frank Miller has no idea how to grasp at anything other than dark, violent, and gritty thus he takes Will Eisner’s groundbreaking comics and tacks it on to his “Sin City” neo-noir universe. Miller doesn’t outright say it to us, but Miller wants us to very much believe that “The Spirit” is a shared universe with “Sin City.”
