Puthiya Geethai presents a conventional storyline that combines elements of drama, romance, and action, typical of early 2000s Tamil cinema. The screenplay follows a linear progression with a clear division between the first and second halves; the first half focuses on character establishment and emotional bonding, while the second half intensifies with conflict and resolution. The pacing is steady, though some sequences tend to drag, affecting the overall momentum.

The film's music by Yuvan Shankar Raja stands out as one of its highlights, with melodious songs that complement the emotional tone of the movie. The background score effectively enhances dramatic moments, although it occasionally becomes overpowering. Cinematography by Ramesh Krishna and Rithuu Ramesh captures the scenic and emotional aspects well, adding visual appeal.

While the songs are well-placed and memorable, the screenplay lacks novelty and relies on familiar tropes. The first half engages with its romantic and emotional beats, but the second half resorts to predictable conflicts and resolutions. Despite these shortcomings, the film manages to maintain audience interest through Vijay's performance and the musical score.

Vijay: Delivered a sincere and earnest portrayal of the protagonist, effectively conveying the emotional depth and resilience required by the role.
