Jason Sanjay made his directorial debut with Sigma. He is the son of famed Tamil superstar Thalapathy Vijay, who is now the Chief Minister of Tamil Nadu. Months after the release of Vijay’s farewell film, Jason Sanjay took his first steps into the industry. Naturally, there was curiosity when the film hit theatres to see what the son of actor Thalapathy Vijay had in store for the audience!
While Sigma did not make great waves at the box office, films always have a way of finding an audience on streaming platforms. With Sigma now making its way to streaming, here’s a look at whether the film’s box office performance was unjustified or if the numbers reflected what it had to offer.

Sigma Movie Review: Script Analysis
Starring Sundeep Kishan as Guru, the film revolves around him and his efforts to keep his library alive. He runs a library that his mother established. Even though the library is running at a loss, he wants to keep it going for sentimental reasons. On top of that, he has a loan of over 1 crore to settle, which his father took out. Now, loan sharks are after him and threaten to take over his library if he fails to repay the amount. He has a support system in RJ Sam, Dr. Neil (Raju Sundaram), and his friend. Believe it or not, the film follows this group of underdogs as they take on a powerful drug lord and a bunch of unhinged criminals.
On the other side is a mix of goons from Tamil Nadu and Andhra Pradesh, all chasing one common goal and a drive and a key. Vincent (Shiv Pandit) is the owner of a gambling chain who also ventures into the drug business after being convinced by Ezhil. Ezhil, in turn, ropes in Veeraayya Reddy (Sampath Raj) as his investor. He has thousands of crores worth of black money through his illegal gun business. Yog Japee plays Y, an assassin who cleans up every mess created by Vincent, including disposing of bodies.
There is a lot happening in the film. Guru and his friends, who seem straight out of an Enid Blyton adventure book, face several challenges and some real threats. But they walk out of these situations as if they were a piece of cake.
Sigma Movie Review: Star Performance
Sundeep Kishan plays the protagonist, Guru. He fits the bill as an underdog but never really steps out of that zone until the end. The film would have been elevated if we had seen a noticeable difference in his attitude and demeanor as the story progressed. Faria Abdullah, as RJ Sam, makes a limited contribution but delivers a decent performance. Raju Sundaram, as Dr. Neil, is more of a comic relief. In fact, his concern for his car has more emotion than the rest of the film.
On the other side, Shiv Pandit plays the typical rich villain who only cares about his gambling business. He does a decent job. Sampath Raj is quite impressive as Veeraayya Reddy, but one wishes the character had more emotional depth and a stronger backstory. Yog Japee fits the bill as an assassin until the film decides to turn him into a man of emotions.

Sigma Movie Review: Direction, Music
Jason Sanjay is the man of the hour. Undoubtedly, there are plenty of expectations riding on him. The young filmmaker has clearly put his all into the film, and that is evident. He shows potential and appears deeply invested in his craft. What he lacks in experience, he tries to make up for with several stylish elements.
The film seems to rely on style to compensate for its lack of substance. Sigma has plenty of stylish shots and edits, but they become overwhelming after a point. All the style is futile if it is not balanced with substance.
The film’s characters fail to create empathy among the audience, despite having sad backstories. The film also seems to have little regard for logic. Otherwise, how does a group of four ordinary people manage to take down dreaded gangsters so easily? And mind you, these criminals have caused several casualties in the police force when officers have tried to take them down. If even some of the best police personnel could not bring these people down, how are four ordinary people supposed to do it? More importantly, the film fails to convince us HOW!
The film’s soundtrack is composed by S Thaman. While the music sounds good throughout, a weak plot makes it difficult for the soundtrack to elevate the overall premise.

Sigma Movie Review: The Last Word
Sigma has ambition, style, and a filmmaker who clearly wants to make a statement with his debut. However, the film gets so caught up in its stylish presentation that it forgets to build a convincing story around it. The characters lack emotional depth, the conflicts rarely feel challenging, and the plot repeatedly asks the audience to overlook logic. While Sundeep Kishan and the supporting cast do their bit, there is only so much they can do with the material they are given. Ultimately, Sigma feels like a film that keeps making things up as it goes along, hoping its style will carry it through. Unfortunately, it ends up going nowhere.
