Kelkatha Sabdam offers a compelling story rooted in the cultural and social fabric of Kerala, with a screenplay that balances emotional depth and narrative clarity. The pacing is measured, allowing the characters' motivations and conflicts to develop organically, though the first half is slightly slower as it sets up the context and relationships. The second half gains momentum with more intense dramatic sequences and resolutions that engage the audience effectively.

The screenplay by Balachandra Menon is thoughtful, weaving together multiple character arcs while maintaining focus on the central themes. The dialogues are natural and contribute to the authenticity of the setting. The movie's music and songs, though not widely documented, complement the mood and tone, enhancing the emotional impact without overpowering the narrative. The background score supports the dramatic moments subtly, reinforcing the film's atmosphere.

Overall, the film is a well-crafted family drama that showcases strong performances and a sincere approach to storytelling. While it may not have the commercial gloss of later Malayalam cinema, its narrative sincerity and cultural resonance make it a noteworthy film from the early 1980s Malayalam film landscape.
