Yes. The theatrical cut showed that he wasn't capable of juggling so many story threads and that he needed to simplify something. As the story is pretty much built aroundIt's late so maybe I read this wrong but it sounds like you think it would have been a better to idea to make Superman less interesting in order to make Batman more interesting. All so Snyder wouldn't have such a hard time.
Batman's redemption with Bruce Wayne narrated bookends, it makes more sense to simplify the Superman aspect in order to strengthen the Batman aspect.
