Nieraali presents a complex narrative that blends psychological thriller elements with introspective drama. The story is intriguing and attempts to explore the blurred lines between reality and imagination through the protagonist's perspective. The screenplay is layered, requiring attentive viewing, and the pacing is uneven with a slower first half that sets up the mood and characters, followed by a more gripping and intense second half.

The film's music by Stephen Devassy complements the mood well, with a subtle background score that enhances the suspense and emotional depth without overpowering the scenes. The songs are minimal but effective in maintaining the film's tone. Cinematography by Santosh Thundiyil captures the atmospheric tension and intimate moments beautifully, adding to the film's overall aesthetic appeal.

While the film's ambition is commendable, some viewers might find the narrative convoluted and the pacing challenging, especially in the first half. However, the performances and technical aspects help maintain engagement, making it a thoughtful watch for fans of psychological thrillers.
