Sigma has the ingredients of an entertaining crime caper because an underworld boss, a group of struggling characters, a gambling den, and a mysterious pen drive are carrying information about Rs 1,000 crore. Jason Sanjay’s directorial debut, however, struggles to turn these ideas into an engaging thriller.

Sigma Review: Crime, comedy, action, and a heist-style storyline are present in Jason Sanjay’s first film as a director. Although Sundeep Kishan leads it, Sampath Raj, Faria Abdullah, Raju Sundaram, Yog Japee, and Shiv Panditt are also there in important roles.
An interesting setup is available at the film's beginning. It explores some people dealing with their own financial problems caught in a trap involving an underworld figure, a gambling operation, and a valuable pen drive. It indeed has enough material to stand out as an entertaining piece.
Sigma, however, struggles to decide its path. It sometimes looks like a goofy crime comedy involving ordinary people. But it later shifts its tone to a more serious screenplay. This is why the film completely struggles to maintain its tonal consistency.
Sigma Movie Review: Story
Guru (Sundeep Kishan) runs a library here. It has an emotional connection with his mother. The library unfortunately fails to become successful. This is why Guru falls into debt and growing interest. Rs 2 crores are needed to save his library. But his situation changes completely after finding a valuable pen drive containing information connected to Rs 1,000 crore.
It pushes Guru into the middle of the dangerous game. The pen drive data, Guru's financial struggles, etc then become the main part of the story. Business magnate and underworld boss Kotlapatti Veerayya Reddy (Sampath Raj), meanwhile, is also involved in a separate crime operation. Ezhil reaches out to him with a plan related to synthetic drugs and a backdoor gambling den operated by Vincent.
These worlds eventually meet later in the storyline.
The basic offerings give enough material to be a crime caper. But the execution doesn't always keep the viewers engaged in the Guru's story.
Sigma Movie Review: Performance

Sundeep Kishan indeed tried to carry the film on his shoulders as Guru. But the role doesn't offer him enough material to show a different side of acting. His financial struggles & mission are clearly established. But the emotional depth isn't present in his role.
Actors from different backgrounds are also available here. It could have created an entertaining group dynamic. Many supporting characters remain lightly developed. Faria Abdullah's character doesn't get enough importance in the overall narrative. Raju Sundaram also feels underused as a doctor despite profession possibility.
Sampath Raj performs the antagonist role in a familiar manner. His character offers the presence needed for the villain of the story. But the writing doesn't give him enough depth.
The performance is overall decent. But the problem is in their character development here.
Sigma Review: Technical Aspects
Sigma's scale is one of the impressive aspects. Jason Sanjay tried to handle e several characters, multiple plotlines, and large action sequences in his directorial debut.
The multi-level parking area action sequence is a prime example of the film's bigger settings. The production values also offer a polished environment here, as Lyca Productions supports a reasonably grand presentation.
The screenplay, however, is the biggest weakness here.
The film has several interesting elements that make it entertaining. An unpredictable crime comedy is initially created through a group of financially struggling people, an underworld boss, a gambling den, a massive amount of money, and a mysterious pen drive.
The screenplay instead frequently depends on convenience to move the story forward. Although some relationships aren't explained enough here, others spend too much time explaining unnecessary concepts.
The linear story indeed helps the audience to follow the large cast and various events. But clarity cannot create suspense, especially when the main conflict doesn't create enough excitement.
A routine approach is also followed in the background score. Although energetic music is there, its placement doesn't feel natural to the story.
Sigma Movie Review: Plus Points
- Sundeep Kishan's presence made the film enjoyable
- Interesting basic setup of a pen drive and Rs 1,000 crore
- The linear storyline made several characters easy to follow
- Some excellent action scenes are also there
- A visual presentation through the production value is also there
- The crime comedy setup also has potential
Sigma Movie Review: Minus Points
- Emotional depth is missing from the screenplay
- The film doesn't maintain tonal consistency
- Many supporting characters remain underdeveloped
- Guru's main plot fails to create enough emotional impact
- Pen drive's mystery takes too long to engage viewers
Sigma Review: Verdict
Sigma has a good collection of ingredients but doesn't come together effectively. A crime boss, ordinary people facing financial struggles, a dangerous gambling operation, a mysterious pen drive, and a massive Rs 1,000 crore angle are present here. It may look as a great foundation for a lively heist thriller on paper.
The screenplay doesn't create enough excitement around these elements here.
Guru's journey should have been the film's emotional centre. His decision to save the library sets a clear reason to pursue the money. But the screenplay doesn't spend enough time making the audience feel his desperation. This is why the victory moments fail to create enough satisfaction.
Jason Sanjay still deserves credit for trying a large-scale story in his first film as a director. He handles multiple characters and stages action sequences with confidence. But the writing makes his efforts feel less impactful.
The film's premise itself is the biggest lost opportunity here. It could have depended heavily on an eccentric crime-comedy setup or committed fully to a tense thriller. Sigma instead keeps moving between these 2 tones.
Sigma may feel familiar and underwhelming for viewers expecting a fresh and gripping heist experience. Its ideas are greater than the screenplay's impact.
