In the Line of Duty IV

Audiences primarily experience **Excitement** and **Humor** from the film's signature Hong Kong action sequences and the bickering, buddy-cop dynamic between Donny and Penny. A significant level of **Anxiety** and **Anticipation** is generated by the high-stakes drug-trafficking investigation, the constant threat from assassins, and the uncertainty of who to trust within the corrupt system. **Satisfaction** and **Joy** arise from successful action resolutions and comedic relief, while **Empathy** is felt for the innocent Luk Wan-Ting caught in the conspiracy. Elements of **Anger** towards the villains and **Surprise** from plot twists and intense action also contribute to the emotional landscape, alongside moments that are **Disturbing** due to the violence and corruption.
