15. Batman v. Superman: Dawn of Justice
For Zack Snyder, this may just be his magnum opus, his greatest achievement so far. Bouncing back from shaky beginnings for DC's new world, ‘Batman v Superman: Dawn of Justice’ achieves everything it set out to do, but ties the superhero genre firmer than ever to greek mythology, religion, concepts of higher beings that have always simmered below the entire make-up of what a superhero encompasses. The future is bright for the DC universe, even in this dim, cloudy world that these iconic heroes populate.
