Zack Snyder makes superhero movies, but his characters don’t act very heroic. Batman v Superman: Dawn of Justice features all the other trappings of the superhero genre: Capes, gadgets, outlandish muscles, punching stuff. But the two stars aren’t noble or chivalrous; they’re violent, aggressive, and angry — mostly at each other instead of the bad guys. In Snyder’s formulation, protecting the world from evil isn’t a gift or a calling; it’s a burden. And that feeling is reflected in the movie itself, a burdensome 150- minute slog about two men fighting over who is in the right when both are very clearly in the wrong.
