Passage Summary: Marife thinks the movie failed because it was a bad mystery that didn't let the audience solve the crime. Nguyen argues that the movie wasn't really trying to be a mystery in the first place, but was actually about the characters' relationship.

Reasoning: Marife argues the film is bad because it failed to provide the clues necessary for a murder mystery; Nguyen counters that the film's primary purpose was to explore a relationship, not to function as a traditional mystery.

Analysis: The disagreement centers on the 'defining characteristic' of the film. Marife applies the rigid standards of the murder mystery genre and finds the film lacking because it didn't provide enough information to solve the crime. Nguyen, however, rejects the premise that the film should be judged as a mystery at all, suggesting the murder was merely a backdrop for a character study. To find the point at issue, look for an answer that asks whether the film should be classified or judged primarily as a murder mystery. Marife would say 'yes,' while Nguyen would say 'no.'
