Frankly, I find the 1.78:1 ZSJL edits the least interesting visually, so I basically skip them. They remind me of that “fill the entire screen philosophy”.
If not 4:3 (which looks fine here), then 2.35:1 for the theatrical feel, but I could give 1.66:1 a try.
The 2.35 for me feels too cropped in and goes against Snyder’s philosophy that I agree with that we often look at heros vertically rather than horizontally.
