I felt the music that plays in the theatrical when The Flash realizes Superman can see him out of the corner of his eye was better. It was weirdly silent in the Snyder Cut and kinda sucked the comedy out of the little bit (it should be funny, Flash makes a funny face realizing).
Maybe I’m just used to the music cue selling the little sequence in the theatrical, and it’s not actually that good from an unbiased perspective, but I dunno. I definitely prefer it over the almost no music version that plays in the Snyder Cut.
