I want to make a comment about that point specifically. I would agree that a film that tackles the power and responsibility dilemma could be ambitious, but my stance is that BvS did not do that. And they had a perfect opportunity to do so.
The most disappointing scene in the film for me wasn't Martha, or Batman murking criminals, or CG Doomsday, or any of Luthors scenes, it was the court scene. When I first saw the trailer, I thought to myself, despite all of the stupid shyt being thrown at the screen, THIS looks like it could be interesting.
Superman having to address a court, speak to the American people, hell speak to the entire world, and take an actual stance on who he is and what his place is in this world.
I was looking forward to that more than anything else in the film. What would be his response? How would he answer to "This is how democracy works. We talk to each other." I thought this could have been a great 5-7 minute scene of truth and character building and thought provoking debate. But no, the court room exploded before Superman could even say a word. So apparently democracy is talking to each other, but this movie is about avoiding that talk, and instead having shyt blow up.
So we don't get to hear him defend himself, we don't get to hear him apologize, or not apologize, or express a counterpoint to the popular narrative, or talk about growing up on a farm, or talk about his ethos, or talk about being a man vs being a God, or talk about how the love of his family or the love of his life factors into who he is, or literally.....anything. He doesn't share a single piece of himself. All we get is him brooding after the explosion. What a wasted opportunity for the film to deliver an interesting and poignant character moment for Superman and one that would explicitly tackle the theme of being a superhero and if people deserve to be saved. That moment should have been used to give Superman, a character so many say is boring and emotionless, a voice that would connect to the audience, in world and out, but instead they used that moment for a piss joke and an explosion.
This is why I say it was an on the surface look at it's themes. The potentially compelling aspects of the film was just undermined at damn near every point, and all that truly was left to like was Batman's action scenes.
At least for me.
