Typical thriller conventions include a subtle start that builds tension, a plot twist, dark mise-en-scene, and fast-paced editing during tense scenes. 2. The media product challenged conventions through atypical music, lighter costumes, and not showing the murder. 3. It used conventions like unexpected plot twists, close-ups describing feelings, and implying a death without showing it. However, it challenged conventions more than using them.
