Director R. Madhan Kumar wanted to make an adult comedy and never bothered about the feelings of the audience. Most of the jokes are hurting. The witty one-liners may shine at times but an overdose of them slips you into boredom. He starts on the movie on a comedy note and in the middle gives it the shape of a thriller. This is so unwarranted and the tonal shifts are unbearable. Some characters become erratic and after some time the humor becomes repetitive. This kills the film to an extent. 

The songs composed by Gopi Sundar are quite mundane but the director ensured to add loads of style to them. Background score can be mellowed down as it’s over-shadowing the scenes at most of the times. 

Cinematography by Raana increases the visual appeal of the film. The songs have been shot stylishly. The witty and ‘double meaning’ dialogue works in some scenes but overall it gives the feeling of a shoddy product. The length of the film is also a major concern and it could have been easily chopped by 20 minutes. 

Mahesh is a story that’s run-on-the-mill and replete with loopholes. Even after the twist it treads a normal path and offers nothing new. The director couldn’t generate drama out of the characters and scenes, and of course, some good performances from the actors. Mahesh is a unipolar film that targets youth with overdose of adult humor. However, it couldn’t sustain the same tone and tempo all through the film.
