Snyder tells the story in the editing room. Every director's different. Fincher has an exacting vision for what he wants to see and averages 50 takes until he gets it (according to a Gone Girl producer)... however, Snyder's way more collaborative and lets the actors do their thing, overshoots to get a ton of raw material, then makes a 5 hour draft of the movie which gets molded into the final film.
There are strengths and weaknesses to each approach, but the latter is generally better for integrated post-production in visual effects heavy films.
That's actually a pretty good approach. I don't want them to rush it, just figured it shouldn't take more than half a year for something in post production. Wonder if they filmed some scenes for Justice League already.
