Baradwaj Rangan wrote, "Poriyaalan is a sort of sibling to Vetrimaaran’s first film, Polladhavan...What sets these films apart from the typical action-thrillers is their texture — you can taste the grit. The storytelling, after (a) flabby beginning, is superbly economic...the film makes good on its promise of a tight little thriller, with mostly adequate performances".^[8] The Times of India gave the film 3 stars out of 5 and wrote, "If the film succeeds, it is mainly because of its screenplay by Mani Maaran. Barring one hard-to-believe turn, it manages to hit the right buttons to keep us on the edge of the seat. It is racy, thrilling and entertaining".^[9] Behindwoods.com wrote, "Poriyaalan has a fairly gripping story, with a commendable, but crisp performance from Mohan Raman".^[10]
