"[36] The Times of India, rated 3.5 out of 5 stars, stating that "Vetri Maaran delivers yet another solid action drama that keeps us engrossed from start to finish.

"[37] Behindwoods rated 3.25/5, stating that "Asuran is an engaging watch with strong performances, interesting plot and an amazing emotional connect with the audience throughout.

"[38] Krupa Ge from Silverscreen said, "Asuran is a bloody revenge saga, that's also weirdly enough about the futility of violence...

Watching the film, after reading the book [Vekkai], feels like dipping in and out of the novel, to wander off to the sides of the pages, filled with detours and notes.

"[39] Gauthaman Baskaran from News18, gave contrary reviews by rating the film 2 out of 5, stating that "Coming at a time when graphic and lurid on-screen violence is being questioned and even condemned, Asuran would appear needlessly falling back to the old formula.
