Passage Summary: A critic thinks making vampires relatable is a mistake; even though complex characters are usually good for stories, we need vampires to stay scary and evil to represent real-world evil.

Conclusion: The recent trend of humanizing vampires in entertainment is a negative development.

Reasoning: Although moral complexity is generally positive, the vampire myth is a vital tool for representing the concept of pure evil, which does exist in the world.

Analysis: The statement in question is a concession, a classic move where an author acknowledges a general truth to appear reasonable before pivoting to their specific exception. By admitting that moral complexity is 'a good thing,' the critic preemptively defends against the charge that they prefer shallow storytelling. Look for an answer choice that describes this as a claim the author accepts but views as overridden by the specific needs of the vampire myth.
