2) Bruce Has Cleaned Himself Up
Along with the new tone and style of Justice League, BvS’s presentation of Bruce Wayne has also undergone a revamp. When we first met him, Batfleck was a depressed alcoholic who was clearly in a very dark place (possibly because of the death of Robin at the hands of the Joker). For Justice League, though, he seems to have a much brighter outlook on life.
[zergpaid]He’s now (in most scenes) clean-shaven, not afraid to crack a smile and instead of trying to kill his fellow superheroes he wants to put a band together. His awkward interactions with Barry Allen and his banter with Wonder Woman really show how much the character has developed since the end of Batman V Superman. Clearly, Superman’s supposed death has had a big effect on the man behind the Bat and has got him to clear up his act.
