Praana offers a gripping storyline that delves deep into the psychological aspects of survival, supported by a screenplay that maintains tension effectively. The pacing is steady, with the first half setting up the premise and building suspense, while the second half intensifies the emotional and psychological stakes, leading to a compelling climax.

The film benefits immensely from P. C. Sreeram's cinematography, which enhances the mood and atmosphere, creating a claustrophobic and intense visual experience. The absence of traditional song sequences aligns well with the film’s tone, focusing instead on a haunting background score that complements the narrative’s suspense and emotional depth.

While the music director is not credited, the background score plays a crucial role in elevating the tension and supporting the film’s psychological themes. The screenplay's focus on minimalism and character-driven storytelling is a strength, though some viewers might find the pacing slow in parts due to its contemplative nature.
