Later, Manoj starts an old age home and his friends and Benny are shown living happily.
Sify gave the verdict "above average" and said "Urumbukal Urangarilla may not offer many surprises and may not be that great for a discerning viewer. But even then this one has its moments for sure and ends up as a decent entertainer".[3]
Metromatinee.com wrote "Urumbukal Urangarilla is nicely executed and technically the movie stands on its feet", also added "Urumbukal Urangarilla is a decent enough effort that engages off and on. There is some well worked out humour and if some avoidable glitches weren't there this one would have endeared even better to the audience".[4]
Indiaglitz.com rated 2.5 out of 5 stars and wrote "'Urumbukal Urangarilla' intends to entertain. There are occasions where things go flat and there is a lull in the narrative. Parts of second half were so. But the movie picked up speed towards the climax and overall feel tended towards being impressive".[5]
Nowrunning.com rated 2.5 out of 6 stars and said "Urumbukal Urangarilla is original and creative, and comes across as an appealing cinematic disquisition on a population that apparently never sleeps. It's a quirky , comic film that provides plenty of silly, and yet inventive fun".[6]
