Though Gethu is not a perfectly impressive thriller, it is a much better outing from both Udhayanidhi and director Thirukumaran compared to their previous films, Nanbenda and Maan Karate respectively. Set in the backdrop of Kumily, the film narrates how an affectionate father-son duo gets entrapped in a murder case and vindicate themselves from the crime.
Despite a largely familiar plotline, the background with which the entire setup is done makes the film a somewhat watchable thriller, but only in parts. Udhayanidhi Stalin plays his role of Sethu perfectly and in Karunakaran's company, he, as always, takes the backseat and lets Karuna take the limelight in comedy portions. However, the needless romance portions between Amy Jackson are quite a headache. The horrible placement of songs annoys viewers to death and Tamil filmmakers don't still seem to understand the mood of audiences.
This could be easily termed as Amy Jackson's most incompetent role for the lack of any purpose to the story or whatsoever. Vikranth as villain comes in slick attires and he gets captivating background score too from Harris Jayaraj to elevate his antagonist image. He is the only silverlining in a screenplay which is otherwise monotonous and moves at a snail pace. Just forget Vikranth's role in Pandianaadu and this one will surely appeal you in most parts. The unfortunate end to his character is a JOKE and even a first-time short film maker could have pulled off the same in better ways.
As always, Sathyaraj does what he is expected to though there is no scope for putting up an impressive show. Technically, the film is topnotch with extraordinary visuals from cameraman Sukumar who showcases the beauty of countryside with pleasing frames.
