Naanum Oru Thozhilali delivers a socially conscious storyline that resonates with the struggles of the working class. The screenplay by C. V. Sridhar attempts to balance drama and social commentary, though it occasionally suffers from uneven pacing. The first half sets up the characters and conflict effectively, engaging the audience with its emotional stakes and character motivations. The second half intensifies the narrative but tends to slow down due to extended dialogues and melodramatic sequences.

The film's music and songs, though not credited here, complement the mood of the film, with background score underscoring the emotional and dramatic moments adequately. However, the absence of standout musical numbers may have impacted the overall engagement. Cinematography and technical aspects maintain a standard quality typical of mid-1980s Tamil cinema, supporting the narrative without overshadowing it.

Overall, the film is a sincere attempt at addressing labor issues with a strong lead performance, but it falls short of creating a consistently gripping cinematic experience due to pacing issues and a somewhat dated screenplay structure.

Kamal Haasan: Delivering a convincing and heartfelt portrayal of a laborer fighting for justice, Kamal Haasan brings depth and sincerity to the role.

Ambika: Provides solid support as the female lead, adding emotional weight to the protagonist's journey.

Jaishankar: Offers a strong presence in a pivotal role, contributing to the film's dramatic tension.
