nice article, why are you posting articles from 2015 when we're talking about last year and how did they underperformed?
the reason why they gave Johns/Berg control is because of quality, it's even stated in the press release. Sure they probably though BvS was gonna hit a Billion but it didn't underperform it made money back and SS did that and then some. If they weren't making money then they wouldn't be making them. WB can't make DC into a film studio, Time Warner has to do that.
Also they already fired the guy who green lit those 2015 movies
