Great, Snyder and Goyer are going to drag both heroes down together now (although Goyer and Nolan pretty much took Batman to rock bottom anyway). Based off of MoS, I'm guessing we'll see Batman grab a pistol and outright shoot someone in this movie. At this rate, there won't be a good live action DC superhero movie until Goyer is too old to write
In MoS, Superman kills Zod and then cries out in devastation over what he had to do. Christopher Reeves' Superman gleefully - and unnecessarily - killed a defenseless Zod at the end of Superman II. Did that bother you?
