In my opinion, each character was made better by Snyder. Flash didn't seem like a cowardly buffoon. Superman played a bigger and more chivalrous role and his strength was shown off. Batman was shown as more of a leader and landed a caring and methodical role. Wonder woman is torn and shows a human aspect. Aquamarine is more heroic. They all mesh together better as a team. You can see the care and passion Snyder poured into this movie. If he's not given the chance to continue with his vision for the Justice League, wB/DC will be doing themselves and all of us a major injustice.
