Innisai Mazhai offers a traditional narrative structure typical of early 90s Tamil cinema, focusing heavily on melodrama and emotional storytelling. The screenplay is straightforward, with a clear division between the first and second halves; the first half sets up the characters and their conflicts, while the second half attempts to resolve these tensions with a mix of sentiment and drama. The pacing is moderate, though some scenes tend to linger longer than necessary, affecting the overall flow.

The film's music and songs, though not credited to a specific music director in available sources, play a significant role in enhancing the emotional tone of the film. The songs are melodious and fit well within the narrative, though the background score is relatively understated and does not particularly stand out. Cinematography and technical aspects remain functional but do not add any distinctive flair to the movie.

Overall, Innisai Mazhai is a film that appeals to audiences who appreciate classic Tamil family dramas with emotional depth, though it may feel dated to viewers expecting more contemporary storytelling techniques or technical polish.
