Holy shit. That sounds interesting.One of the things that became most apparent from Mr. Blue's fan edit of BvS was how the first half of the film is very much a Batman film with a Superman subplot, then the two clash and it becomes a Superman film guest-starring Batman & Wonder Woman. I didn't think that would work, but putting the climax of Superman's crisis of faith (the Pa Kent mountaintop chat) at the beginning of his character arc really worked for me in terms of setting up where Clark is at the start of the story and gives the ending of Man of Steel even more weight as it had a profound impact on both of the main characters.
The whole Capitol explosion stuff is gone. It's unnecessary. It's only there to make Superman lose faith in himself, which this fan-edit accomplishes by having that be caused by his guilt over the destruction during MoS. This also helped re-contextualize Clark investigation of The Batman's sudden change in tactics by branding them, leading to their deaths in prison. Lois, of course, doesn't get as much to do until the second half, but there's enough of her and Clark's scenes that their love for each other remains very clear so that Clark's sacrifice at the end still hits.
