Naalaiya Theerpu, marking the debut of Vijay as a lead actor, is a typical early 90s Tamil action drama that relies heavily on familiar tropes of revenge and heroism. The story is straightforward and predictable, with a screenplay that moves at a steady but unremarkable pace. The first half sets up the conflict and characters adequately, though it tends to drag with melodramatic sequences and exposition-heavy scenes.

The second half picks up momentum with action sequences and confrontations, but the overall narrative lacks depth and innovation. The film's songs and background score are functional but do not leave a lasting impression, serving mostly as fillers rather than enhancing the emotional or dramatic impact. The music director's contribution is minimal and does not stand out in the film.

Cinematography and technical aspects are basic, reflecting the modest production values of the time. While the film succeeds in introducing Vijay to the audience, it does not offer much in terms of cinematic excellence or storytelling finesse. Overall, Naalaiya Theerpu is a nostalgic watch for fans of Vijay but falls short as a compelling cinematic experience.

Vijay: A debut performance showing promise but limited by the film's weak script and direction.

Keerthana: Adequate as the female lead, though her role is underwritten.

Radha Ravi: Effective as the antagonist, bringing intensity to the role.

Mansoor Ali Khan: Typical villainous portrayal with limited scope.
