Tamil filmmakers like Lokesh Kanagaraj, Nelson Dilipkumar, and Karthik Subbaraj have redefined commercial action cinema with fresh storytelling and engaging screenplays. Naturally, there was curiosity surrounding Sigma, as it marks the directorial debut of Jason Sanjay, son of actor-turned-politician Vijay.
Unfortunately, the film starts on a dull note and struggles to recover. Within the first fifteen minutes, it becomes evident that Jason Sanjay has chosen a very old-school commercial format rather than presenting something fresh. From the hero’s introduction to the comedy sequences, very little creates excitement.
The story revolves around Guru (Sundeep Kishan), who runs an audio library from his home in Visakhapatnam and lives with his mother. He is neck-deep in financial trouble, with a debt of ₹1 crore hanging over him. Desperate for money, Guru enters a casino run by Vincent (Shiv Panditt), along with his partner RJ Sam (Faria Abdullah). There, he gets hold of a video exposing Vincent’s illegal drug and gambling activities and decides to use it to clear his debts. Things soon take a dangerous turn when a mysterious key connected to Veeraiah Reddy (Sampath Raj) comes into the picture.
The first half spends too much time establishing Guru’s problems and financial struggles. Even after the villains are introduced, the narrative lacks urgency. The conflict between the hero and villains resembles a repetitive cat-and-mouse game, and the screenplay rarely generates tension or excitement.
The film appears to draw inspiration from several Hollywood-style crime thrillers, but the execution never reaches that level. The storytelling feels outdated, and the screenplay lacks the freshness expected from a debut filmmaker. Several scenes feel stretched, making the film drag considerably, especially in the second half.
Jason Sanjay fails to bring novelty either as a writer or as a director. The subject itself feels like something that would have worked a decade or two ago. While there is visible production value on screen, the writing does not support the scale of the project.
Thaman’s music is another disappointment. None of the songs leave a lasting impression, and the background score only works in a few isolated moments. The cinematography is functional, but the technical departments do little to elevate the material.
Coming to the performances, Sundeep Kishan delivers a routine performance that is in line with the character’s requirements. He does what is expected, but the role does not offer him much scope to shine.
Sampath Raj is dependable as always, though his character feels familiar. Faria Abdullah gets a role with some importance and performs sincerely. Raju Sundaram’s comedy track fails to generate laughs, while Shiv Panditt and the supporting cast leave only a limited impact.
One particularly puzzling moment comes towards the end when the film attempts to justify the title Sigma. Instead of creating clarity, the scene adds to the confusion, making viewers wonder about its relevance to the overall narrative.
Sigma had the opportunity to be a fresh action thriller, especially with Jason Sanjay making his debut as a director. However, the film ends up feeling like an outdated commercial entertainer filled with routine characters, predictable conflicts, and a weak screenplay. In the end, Sigma fails to capitalize on its premise and leaves very little impact.
