Since its announcement last year, Sigma has generated considerable curiosity. Chief Minister Vijay’s son being the director, boosted the hype, while the film has also been trending on social media with promotions.
Touted as Sundeep Kishan’s ambitious outing, the film comes with considerable expectations. The question is whether it lives up to the hype.
Story
Guru (Sundeep Kishan) runs a library and struggles to make ends meet. He and his girlfriend, RJ Sam (Faria Abdullah), are in desperate need of money. Guru eventually discovers that an antique key he comes across could lead to a stash of money stored abroad.
The key belongs to Veeraya Reddy (Sampath Raj), who is believed to have been killed in a shootout. When Guru finally gets hold of the key and attempts to escape, the supposedly dead Veeraya Reddy suddenly reappears. What happens next forms the rest of the story.
Performances
Sundeep Kishan plays a character that offers him very little scope to do anything different. His performance is largely in his familiar style, with neither the character nor his portrayal bringing anything particularly fresh to the screen.
Faria Abdullah gets a largely forgettable role and has little impact on the proceedings.
Raju Sundaram and Tamil comedian Anbu Thasan are brought in for comic relief, but their intended humour rarely works and becomes tiresome. Sampath Raj plays his part in his usual style, while Shiv Pandit is adequate.
Technical Aspects
The film does not have a single song that makes an impact. Thaman’s background score is just about adequate, while the cinematography is functional.
The bigger problems lie in the writing and editing. The screenplay lacks coherence, and the editing fails to give the narrative the pace it desperately needs.

Analysis
Sigma marks the directorial debut of Jason Sanjay, son of Tamil superstar and politician Vijay. Although the film is a dubbed Tamil production, it features Telugu actors Sundeep Kishan and Faria Abdullah in the lead roles.
The debut director struggles most with the writing. The film would have benefited from an experienced writer, particularly for the screenplay and dialogues.
The story starts with a template that has been used countless times in money-heist thrillers. From the title cards and character introductions to the heist episodes, almost everything feels familiar. There is very little that feels fresh or exciting in either the plot or its execution.
The film opens by establishing Sundeep Kishan’s Guru as a financially struggling man trying to keep the family library running. The very idea of someone running a private library feels dated in the present-day setting, and the film does little to make the premise interesting.
Guru and Sam’s introductions and their initial interactions are painfully dull. The first half spends a great deal of time establishing Guru’s financial troubles, repeated setbacks, casino gambling and fights, without creating enough dramatic interest.
The film’s biggest problem is that it takes far too long to get going. The entire first half is flat and predictable. The comedy track involving Anbu Thasan and Raju Sundaram only adds to the frustration rather than providing relief.
The second half, when the story moves fully into money-heist territory, should have injected some energy into the film. Instead, it becomes increasingly absurd. The narrative keeps dragging without generating either tension or excitement. The villains fail to make an impact, and the so-called twists do little to surprise.
Even the item song, which is presumably intended to provide a change of mood, disrupts whatever momentum the film manages to build.
The climax takes the film further into absurd territory rather than providing a satisfying payoff.
Overall, Sigma is a patience testing thriller let down by weak writing, poor characterisation and an unnecessarily stretched narrative. Jason Sanjay’s debut shows his inexperience as a writer. What could have been an engaging money-heist thriller instead turns into a tedious watch.
Bottom Line: Totally Flat
