The plot of a simpleton who rises to become society's savior always works in movies, especially when the necessary components are present. The fundamental premise of Dhanush's Vaathi is quite strong and stands up for a cause, despite the fact that it appears to be largely based on Hrithik Roshan's Super 30.
Vaathi begins in the present and follows a group of three students as they piece together the past of a strange person using an old VCD cassette. We learn that the individual is Bala (Dhanush), a former assistant maths teacher who becomes entangled in the tumult of educational privatization in the 1990s.He is left without parental or administrative assistance to prove his mettle in a closed government school.
The central theme of the novel is how he overcomes obstacles to live and use education to change the lives of impoverished students.

Vaathi is a movie in which the hero uses modest means to achieve greatness, but the undemanding screenplay only provides a few payoffs, despite several sequences being well-set up. The script also needs more moments like the one when Bala shows how caste is pointless and the classroom transforms into a microcosm of society; if there were more of them, we would have seen something like to the 2007 American film Freedom Writers.

The movie also has a lot of one-dimensional characters who initially had promise. The Tanikella Bharani and Hareesh Peradi characters don't feel the plot to be worthwhile. The screenplay places Muthu, played by Ken Karunas, in some intriguing situations, while Meenakshi, played by Samyuktha, is reduced to a non-player. When it comes to the actor at the centre of it all, you can only feel bad for Dhanush because he does try to support the movie by himself, even during its average sections. However, there isn't enough information on paper to support him.

The willingness of Tamil filmmakers to explore societal concerns, even in films that are just comedies, is one of the most distinctive characteristics of their work. This is something that the business has always done, and Venky Atluri's Vaathi (which was concurrently released in Telugu as "Sir") is another example.

Director Venky Atluri's first Tamil film is titled Vaathi. Tholi Prema (2018), his Telugu debut, was a tremendous success. Vaathi, which also marks actor Dhanush's comeback to the action genre after two duds, has being eagerly anticipated (Maaran and Jagame Thandhiram).
