When you try to induce unnecessary commercial elements in a very interesting and engaging concept, the result is Courier Boy Kalyan. The film which could been a decent thriller is seriously obstructed with the arrival of songs and a hurried up climax. But a breezy first half, and some engaging thrills salvage the film which ends up as just an ok watch.

Plus points are Nithin, basic plot and a couple of thrilling episodes in the second half. The romance thread in the film offers no freshness. Though the length is 104 minutes, there is still a need to edit songs and a few irrelevant comedy episodes. The screenplay should have been more arresting. On a whole, Courier Boy Kalyan is an attempt to blend in family elements and romance to an interesting thriller story.
