Man of Steel has a very Americana feel about it, being shot mostly handheld, giving it a lived in feel and a sense of urgency to the action rarely seen in this genre on this scale. BvS is downright operatic. The shots are big, longer, wider, steadier, with a more classically cinematic feel, because it's dealing making the duel more than just man vs. alien, but rage vs. compassion. Fear vs. understanding. Justice League has a distinctly more "alive" quality about it based on what we've seen thus far. But that works because we've dealt with our heroes being brought to their lowest point. It will feel more powerful because BvS went so dark, which is how it was planned from the beginning.
