Superman is DCs Last Hope Against Marvel
As you can see, DC is fighting a losing battle against Marvel Comics in the Box Office...
Not only that, but Marvel is upping up the ante not just with the three staged Avengers set up and independent films, it's also realeasing a shit load of other films. Dare I say it will keep up with the shit storm of Star Wars shit about to be flooding Hollywood.
However, as you can see - Superman was a major character and his film made a lot of money, even though it got bad reviews. This is because of how iconic he is, everyone flocked to see him at first. Zack Snyder's 300 was a hit, I personally thought what he did with Watchmen was miraculous, and he has TDK's Goyer writing his script, and this film has a huge budget, courtesy of Nolan.
