The film has a purely written script and has either the music or the performances to carry it through. Only the comic elements in the film and Santhanam make it most watchable." "in.com" said, "Pattathu Yaanai is not boring! Boopathy Pandian has come up with decade old story again and has stick with the formula of songs, action, sentiment and comedy. The problem is the strong script and greater strength to integrate all these commercial elements in screenplay properly. He is good at mixing humour at most expected circumstances and that’s the only thing that worked to some extent in this film with the help of Santhanam.". Prashanth Reddy of "Desimartini.com" said, "Pattathu Yaanai is an action-comedy at heart where momentary spurts of action are just a relief from what would have otherwise been a full-fledged comedy. The film makes more sense when you look at it as a comedy about the exploits of a bunch of wedding caterers who run from trouble and arrive in Tiruchy- only to find more trouble." and added "But because of the film's "mass entertainer" aspirations, it brings in utterly necessary characters, like the heroine, who adds greater value to the story, besides being heavily sentimental. In spite of it, the film still manages to entertain and how- thanks to the one man who has been consistently delivering time and again: Santhanam,". "Behindwoods" said, "Vishal has sincerely delivered what is expected from him. If you were to expect Vishal to showcase his six pack abs, you would not be disappointed but the twist in the tale comes from the villain who removes his shirt to flaunt his chiseled torso. Action scenes though well choreographed, offers nothing new." and added "Aishwarya Arjun looks emaciated but fits into her docile role. Pattathu Yaanai is an apt vehicle for the debutante and there is not much for her to demonstrate in the department of histrionics." "Indiaglitz.com" said, "Pattathu Yaanai' is the same new wine. If you have to consider the exclusion of Chennai city in the story, casting the heroine as a high school girl, instead of a college student and villain gang with a light sense of humour, then it is old wine in new bottle."
