Nenjile Thunivirunthal delivers a straightforward storyline that aligns well with the action-drama genre popular in early 1980s Tamil cinema. The screenplay is linear and focused, with a clear division between the first and second halves; the first half establishes characters and conflicts with moderate pacing, while the second half intensifies the drama and action sequences, maintaining audience engagement.

The film's pacing is steady, though some scenes tend to linger longer than necessary, which slightly affects the narrative flow. The songs composed by Ganesh and Shankar blend well with the film's mood, offering melodious and situational tracks that complement the story without disrupting its momentum.

Cinematography by D. D. Prasad captures the rural and urban settings with clarity, supporting the film's dramatic tone.
