Though not a perfect ride, Udhayam works well as a road movie that is quite crisp and engaging.
The final product does not disappoint but at the same time this ride through NH4 has some speed breakers, most prominent being the dubbed feel of the film.

Technical team has done their work well enough to lift the film up. G V Prakash's RR revs up the moods where needed and his much popular 'Yaaro Ivan' has also been picturized well.
