O2 was described as a "pretty engaging survival drama which distinguishes between brute force and real heroism".[7] Manoj Kumar from The Indian Express gave 3 out of 5, stating that "Nayanthara pulls off a splendid performance in this largely engaging thriller".[8] Priyanka Thirumurthy from The News Minute gave 3.5 out of 5 and wrote "it is actor Nayanthara who shoulders this weight splendidly and credit must be given to the director GS Viknesh for writing a role where a woman can be unapologetically selfish, self-serving and downright violent to protect her own. Nayanthara skilfully shoulders O2".[9] Logesh Balachandran from The Times of India rated the film 3 out of 5 and wrote "Debutant director GS Viknesh's O2 may not be an edge-of-the-seat thriller, but its powerful enough to keep you hooked throughout with distinct characters". The reviewer concluded that it was "An engaging survival thriller".[10] India glitz rated the movie 3 out of 5, stating that "Nayanthara's film O2 is a decent survival thriller uplifted by good performances".[11] Haricharan Pudipeddi from Hindustan Times wrote "Nayanthara's film is a race against time survival thriller set inside a bus", and described the Nayanthara -Rithvik chemistry as a highlight.[12] Latha Srinivasan from Moneycontrol praised the film's concept while criticising its execution. However, the critic said "It's the performance of Nayanthara and Rithvik that keep you engaged". Ashameera Aiyappan of Firstpost rated the film 2 out of 5 stars and wrote "O2 falls flat despite convincing performances from Nayanthara and Ritwik".[13]
