Neru offers a compelling narrative that combines Jeethu Joseph's trademark suspense with strong character-driven storytelling. The screenplay is tightly woven, maintaining a steady pace throughout the first half, which effectively sets up the stakes and introduces the key players. The second half intensifies the drama with well-executed twists and emotional confrontations, though some scenes may feel slightly drawn out for viewers seeking brisker pacing.

The film's music, composed by Vishnu Shyam, complements the mood effectively, with songs that blend seamlessly into the narrative without disrupting the flow. The background score enhances the tension and emotional beats, particularly in the thriller sequences, adding depth to the cinematic experience.

Visually, Satheesh Kurup's cinematography captures the essence of Kerala's landscapes and urban settings with a crisp and immersive style, supporting the film's tone. Overall, Neru balances its dramatic and thriller elements well, though it occasionally leans heavily on familiar tropes, which might affect its freshness for some audiences.
