Berry Mutants exist. The careers of David Arquette and Emily Watson prove it. Instead of focusing on what a mutant is, the film opens and we are thrust into a world where mankind is trying to find a way to monitor the mutant population through the legal system.
Fear is a strong weapon.
Extremely powerful mutants, they stand on opposite sides regarding the value of human life. At that point, we are introduced to our cast. As a result, the film doesn't devote too much time to focus on origins, instead unfolding its ambitious storyline and character development. As a result, the film successfully captures the comic. People who read the comic know that for every 20 pages of story, there's 3 or 4 pages of action.
