That’s Zach Snyder in general. The only way to really watch his films are extended cuts, because the theatrical cuts tend to cut out all the exposition and focus on the core of the movie. But the core of the movie doesn’t make much sense without the exposition. The result is an overlong movie that feels like it should be shorter, but nothing can really be trimmed because the film tried to do too much. BvS is a prime example of this.
I think the guy gets way too many ideas in his head and has trouble telling a single, focused story with them.
