Kollywood Today wrote "As a whole, Ammuvaagiya Naan is a film that has attempted to can a bold theme with different approach and thank god, there are no unwanted commercial elements present here."^[5] Chennai Online wrote "'Ammu...' is a film, which, despite its flaws, and its fairy tale look at the not-so-pleasant world of sex workers, is refreshingly different and worth a watch".^[6] Mu. Maran of Kalki appreciated the acting of Parthiban, Bharathi and other actors, cinematography, dialogues and background score and concluded saying slow screenplay, not so memorable songs, some of the scenes which could have handled decently despite the necessity for the film are some of the flaws, in the midst of action films, Ammuvagiya Naan is a wonderful Tamil cinema.^[7]
