Falling in love with two people at the same time is it not an unexplored territory in Tamil cinema, and has been done by stars like Rajinikanth and mohan. In kaathuvaakkula rendu kadhal, Vignesh shivan  also deals with a similar topic in his own style, laced with humour and emotions. however, the treatment here doesn't let you enjoy the movie to the fullest in the way it was intended to. The plot is very predictable and the situations just seem to happen without any real conflicts. The film starts with a young boy, Ranjankudi Anbarasan Murugesan Boopathy Oohondhiran alias Rambo, leaving his sick mother believing that he has a jinx over his life and his very presence itself might cause her harm. A few years later, we are shown a double-living adult, Vijay Sethupathi, who is a taxi driver in the morning and a bouncer in the evening. In his two lives, he falls in love with two women of opposite personalities, khathija (Samantha) and kanmani (Nayanthara) . After the two women finally proposed to him, Rambo felt that the curse of his life had been lifted, and he got everything he wanted in his life with double help. The problem arises when reality strikes him and he is forced to make a choice between his two lovers. The plot is simple, but Vignesh shivan creates another universe for the three protagonists with an interesting backstory. At first everything looks like it's going in the right direction, but as the movie progresses, the plot weakens. It becomes another romantic comedy with no purpose at all, and cannot meet the dream combination of Vijay Sethupathi, Nayanthara and Samantha. What is missing here is the actual conflict and complicity associated with 3p relationships. Just as he expects things to go in a serious direction, Sivan waters it with a humorous take. His treatment may be fine for movies in the romantic comedy genre, but some scenes may be incredibly written to involve the audience. The scene where Nayanthara takes care of her sister and her brother with a disability and Setupati connects with them is beautiful, and perhaps Sivan could have learned more about them. Rambo's individual journeys with two women are interesting enough, but as the world clashes,  the film loses steam and can elicit laughter here and there. The big savior of the movie is Aniluda, who makes it a safe experience with his inspiring numbers and emotional background music. However, the duo Anirudh and Vignesh Shivan, who reminded us of a magical experience at Naanum Rowdy Thaan, can only partially reproduce the same thing. The mere presence of Vijay Sethupathi, Nayanthra, and samantha helps to enhance even ordinary scences, despite sloppy writing. The single shot scene, where Vijay Sethupathi has a long dialogue, shows the skills of the actor and how good actors make the scene interesting. Nayanthara and Samantha complemented each other well and proved why they are the most sought after actresses in the business.
