The movie has mostly received positive reviews from critics.
IANS gave the film 3.5 stars out of 5 and wrote, "
Thirudan Police is your average revenge drama that gets salvaged by some great comedy, the kind audiences don't mind paying for....(it)shows how comedy can do wonders in a story if one knows how to use it".
Rediff gave 3 stars out of 5 and wrote, "He (Caarthick Raju) has cleverly refined in every element, be it action, comedy, romance or emotion, keeping it light, interesting and highly entertaining", calling the film "a delight to watch" and "definitely a commendable effort".
Sify called the film "a nice fun ride" and further added, "It is well-written comedy entertainer which also has a strong emotional story about the bonding between a father and son. And also an entertaining hide and seek thriller featuring a cop with a vengeance".
Deccan Chronicle gave a rating of 2.5 stars and wrote, "For a debut directorial venture, Caarthick Raju's
Thirudan Police is a commendable end product that manages to prop itself up as an entertaining thriller with a smidgen of comedy mixed in".
Baradwaj Rangan wrote, "the film's biggest (and nicest) surprise is that this revenge drama is treated like a comedy.
Thirudan Police pees all over that most hallowed of tropes: the love for a parent. The upshot is that the narrative has no real emotional charge – but that's fine. The trouble is that this one-note gag (about Vishwa's father) is stretched out too long. Also, there are tonal issues...but the real problem is when the film gets all serious on us. But the climax is such fun that we forget what came earlier".
The Hindu wrote, "Caarthick Raju's real strength is comedy. A Ramarajan-style punch quite early in the film...signals this. The climax sequences confirm it. You're happily willing to suspend all disbelief when the scenes are as funny as they are at the end... As you walk out, you can't but wonder if the director, after noting all the laughter at the end, rues his decision not to have made a full-fledged comedy".
The Times of India gave 3 stars out of 5 and wrote, "
Thirudan Police wants to be a sentimental story as well as a comedy. The tone is uneven – one moment we are asked to get sentimental and then in the next, we are told to laugh. This is jarring, as is the manner in which the film turns from an emotional father-son tale to a comedy. To the director's credit, he does this with confidence that we begin to enjoy the humour after initially feeling disconcerted". == References ==
