Film critic R. G. Vijayasarathy of IANS wrote that "If you are a fan of weepy, sentimental film with old style narration, then 'Anna Thangi' may well please you". Chitraloka wrote "The story of 'Anna Thangi' is as old as the days of 'Anna Thangi'. True. What father has done the son repeats but in the 21st century. 'Thavaru' brand Director Saiprakash has added the extra luxury for the film producer Prabhakar has borne it. Lorry loads of sentiments makes your eyes to collect tears. Finally when you return from the theatre such a situation should not come to brother and sentiments! But where are such brothers and sisters in this world yaar!". S. N. Deepak of Deccan Herald wrote "The first part of the film is the celebration of the brother-sister relationship while the other part deals with the ups and downs of their life. Saiprakash who is an expert in portraying such things does his job neatly. What is new about this film is that he has retold the old story of brother-sister bond".
