If the plot was taken seriously, Undercover Punch and Gun could easily be accused of derivative content. The sheer amount of undercover cop narratives in the history of Asian action has made this the case, and Undercover Punch and Gun throws us directly into this exact scenario. It is with variation in tone, and where the film goes with the predictable premise that promises some originality. First of all, despite an emphasis on martial arts action in the storyline, the tone is comedic enough to consider the parodic elements of the narrative. At least to some degree, the derivative elements feed into the humor in this regard.
