Mersal Review: With Mersal, we have got this year's most engaging mass masala movie. It has a relatable theme (even though the medical field has been the target for many films), star power, punch dialogues that double up as political statements, emotional scenes that make us care for its characters, a message that connects with us, colourful visuals, peppy music, and masala moments that keep you cheering for the hero(es).
The film begins with the kidnapping of a few individuals and the arrest of Dr Maaran (Vijay), who, the investigating officer Rathnavel (Sathyaraj) believes is the mastermind. As he interrogates the doctor on why he let himself get captured, he learns that it is actually Vetri (Vijay) , a magician - and a look-alike of Maaran - who has committed these crimes. How is Vetri connected to Maaran and what does he want?
Taking a leaf out of his guru Shankar’s playbook, and a lot of inspiration from masala movies of the yesteryears (from MGR's dual-role films like Kudiyirundha Koyil and Neerum Neruppum to triple-role films like Rajinikanth's Moondru Mugam and Kamal Haasan's Apoorva Sagotharargal), Atlee has given us a wholly satisfying mass-hero film. And his decision to bring on board Vijayendra Prasad, the writer of Rajamouli's films, is a masterstroke (Atlee and Ramanagiri Vasan, who has written the dialogues, are the co-writer). The fingerprints of the Baahubali writer can be found in many scenes - like in the scene in the flashback portion, where Thalapathy (Vijay), the father of Vetri and Maaran, has to save people trapped in a fire. Thalapathy brings down a giant wheel singlehandedly, and it feels like a nod to Baahubali, where Prabhas stops a huge statue from falling down. There is also another distinct Baahubali moment where a child raises its hand even as its father goes down promising the hands of his people will raise up.
Like the masala films that it tries to emulate, the film also has a longer duration. We get two flashbacks, one before the interval, and another post it. Atlee also gives a romantic track each to Vetri and Maaran. But these are just generic ones, but the two actresses, Kajal Aggarwal and Samantha, manage to provide some lighthearted moments in the miniscule time that they get. But the director makes up for it with the romance in the flashback involving Thalapathy and Nithya Menen, once again, comes up with an affecting performance.
The success of any revenge-based masala movie is the effectiveness of its antagonist and it is here that Mersal feels a little underwhelming. Atlee seems to have wanted an antagonist who is suave and sinister, but perhaps because we have only recently seen a terrifically over-the-top SJ Suryah in Spyder, his characterisation of Daniel Arockiaraj here comes across as a rather subdued villain, even though the actor does well.
However, the director doesn't disappoint when it comes to his hero. He gives all the three characters moments to showcase their heroism (the camera almost worships its subject). We have seen Vijay reel of punch dialogues, dance like a dream and fight effortlessly, but there is a scene where, as Thalapathy, he breaks down, and the actor shows that he can also pull off emotional scenes. When you have a mass hero in full form like Vijay is in the film, how can things go wrong? The story of the movie revolves around a doctor who is falsely charged with a crime he did not commit. The doctor discovers the conspiracy .involving the medical industry and sets out to expose it  .the movie has elements of action ,romance and drama.

overall ,the movie recieved positive reviews  from both the audience and critics  alike for its storyline,performances,music,and visuals.

it became a commercial success  and grossed over 260 crores….
