K. Vijiyan of New Straits Times said the film "proved easy to watch despite running two hours and 45 minutes".[7]Kalki wrote the film flows like a river without the rush of a commercial film and like an art film without the speed of a turtle.[8] D. S. Ramanujam of The Hindu wrote, "The mental conflict of a husband suspecting the platonic relationship of his wife with a male friend, known to her for long, attains glorious proportions, thanks to the wonderful performances of Raghuvaran (husband), Karthik (friend) and Revathi". He also appreciated the writing and direction of Adhiyaman.[9]
Remake
Adhiyaman chose to direct his first Hindi film and began remaking Thotta Chinungi in Hindi as Aap Mere Hai Sanam in early 1998.[10] The film languished in production hell and was eventually released in 2002 as Hum Tumhare Hain Sanam.[11][12]
