I’ll second the point that Lois’s intervention (and character overall) was better in the Whedon Cut (though the Snyder Cut was better overall). Having Batman bring her in as the “big gun” has the added benefit of neatly making sense out of & resolving Future Flash’s “Lois is the key” message from BvS. I really don’t like the way that, even after Superman is revived, Snyder goes out of his way to suggest that a Superman back in his right mind could still be turned evil simply by killing Lois.
