Sigma Twitter review: 7 tweets you must read before watching CM Vijay's son Jason Sanjay’s Tamil directorial debut starring Sundeep Kishan

Jason Sanjay, son of Tamil Nadu Chief Minister and actor Vijay, has finally made his directorial debut with Sigma. The Sundeep Kishan-starrer arrived in theatres today, October 2. The film was earlier scheduled to release on July 31 but was later postponed. With Sigma marking Jason Sanjay’s first film as a director, there was considerable curiosity around how audiences would respond to his work. The film also stars Faria Abdullah and is positioned as an action-adventure heist entertainer. Audiences went for the first-day-first-show screenings, and early reactions have now started appearing on X, with viewers divided over the first half but praising certain performances, action sequences and music.

Netizens review Sigma

One X user shared a positive reaction after watching the first half and praised the film for being story-driven. The viewer pointed out the twists and turns, background score, songs and the action-packed interval block. Sundeep Kishan’s combination of action and comedy also received praise.




The viewer also had a positive word for Jason Sanjay’s first attempt at direction, describing it as mature despite this being his debut. The reaction suggested that the first half had set up the story well and ended on a strong note, while also expressing curiosity about the second half.



However, another viewer had a different take. According to the reaction, the first half did not establish a strong enough story, while the introductions and conflicts involving the characters lacked an emotional connect. The user hoped that the second half would bring something more interesting and engaging.


Another X user called the first half good, although they felt the movie took some time to pick up. The viewer said, "Sigma - Good first half It starts off slow, but gradually picks up really well and ends with a good interval.. Thaman and Kishan owned the first half. Such a good actor. Thaman’s two songs were a highlight."

Sundeep Kishan, Thaman S get praise

Sundeep Kishan appears to be one of the more consistently appreciated aspects of the film in the early reactions. Apart from his performance in the action sequences, viewers have also highlighted his comic timing.

One reaction said the comedy worked well in theatres and that the audience responded positively to the humorous portions. The viewer also praised the casting and Sundeep Kishan’s characterisation.




Music composer Thaman S has also received attention. One viewer specifically praised two songs in the first half, while other reactions have highlighted the background score. Thaman has composed the music for Sigma, which also features Faria Abdullah, Raju Sundaram, Sampath Raj and Shiv Panditt among others.



Another highly enthusiastic reaction called the film a “blockbuster” and praised its characters, direction, visuals, music and performances. The viewer felt that the different elements came together effectively and described the film as an experience.

However, these are individual audience reactions posted on social media, and the early responses remain mixed rather than unanimous.

What is Sigma about?

Sigma is a heist-based action entertainer directed and written by Jason Sanjay. The film revolves around a high-stakes heist connected to the operations of crime boss Kotlapadi Veeraiya Reddy, played by Sampath Raj. The cast also includes Faria Abdullah, Raju Sundaram, Shiv Panditt, Anbu Thasan and others.

The film is produced by Lyca Productions, with Thaman S composing the music. Jason Sanjay’s entry as a director has been one of the biggest talking points around the film, particularly because he comes from a prominent film family.



Sundeep Kishan had earlier spoken about why he agreed to work with Jason. The actor said the young filmmaker personally narrated the story to him and that the narration gave him confidence in the project.

The release also comes as Jason attempts to establish himself as a filmmaker. His father Vijay, who is now Tamil Nadu’s Chief Minister, has stayed away from promoting the film, with reports saying the decision was intended to allow Jason to build his own identity in cinema.

For now, the first-day reactions suggest that Sigma has found appreciation for Sundeep Kishan’s performance, comedy, action, music and Jason Sanjay’s direction, while some viewers remain unconvinced by the first-half writing. Stay tuned!
