The ending to Man Of Steel was a little controversial, for it was not simply Superman saving the day. As Zod expired, and Superman rejoiced in saving Metropolis, many noticed that while “victorious” Superman left Metropolis in a pretty bad place. Buildings destroyed, blocks leveled, and there was no way everyone got out, so why be happy?
This thought hasn't escaped Man of Steel and Batman v Superman: Dawn Of Justice director Zack Snyder. While speaking with EW, Synder speaks on the notion of the body count at the end of the film, “I was surprised because that’s the thesis of Superman for me, that you can’t just have superheroes knock around and have there be no consequences.”
Continuing with this, Ben Affleck, who will be portraying Batman/Bruce Wayne notes, “One of the things I liked was Zack’s idea of showing accountability and the consequences of violence and seeing that there are real people in those buildings, and in fact, one of those buildings was Bruce Wayne’s building so he knew people who died in that Black Zero event.”
It seems that Batman not only has a protective interest in fighting Superman, but also a personal one. Dawn Of Justice will release March 25, 2016.
