Thulasi of Kalki wrote today everyone believes in grandeur and great heroes. The director of this film relies on story and poignant sentiment. More than that he relies on the screenplay, so hope is not wasted.[4] D. S. Ramanujam of The Hindu wrote "A team of comedians keep the fun sometimes with `sickly' jokes, right through Anu Pictures' Neela Kuyil, a small budget movie set to catch the eye of the ordinary viewers of the mofussil. Priyadarshan's story and screenplay are not powerful enough to make director Ashraf draw something more from the artistes, Vadivelu and Senthil, both working in tandem as cheats and tricksters, cornering most frames. Hero Pandiyarajan is sidelined in a role not suited to him a lamenting hero ruing his misfortune".[5]
