Story:

Set in Vizag, Sigma follows Guru (Sandeep Kishan), who runs a home library that was his mother’s favourite place. However, his father’s ₹1 crore debt puts him under immense pressure to arrange money.

Guru eventually learns about a dangerous drug called Ceaser, which is handled by Vincent. With solid evidence against him, Guru blackmails Vincent for money. However, the entire operation is controlled by international smuggler Kotlapadi Venkata Reddy (Sampath Raj), who has much bigger plans.

What happens to Guru after entering this dangerous world and whether he manages to get the money forms the rest of the story.

Plus Points:

Sandeep Kishan completely trusts Jason Sanjay’s vision and delivers a sincere performance. He puts in an honest effort throughout the film and handles the action sequences reasonably well.

Faria Abdullah gets limited screen time and appears in only a few scenes. She does an adequate job within the scope of her role.

Sampath Raj gets a more substantial role and delivers a dependable performance as the antagonist. He brings the required authority to his character with ease.

Minus Points:

The biggest drawback of Sigma is its routine and outdated storyline. While there is nothing wrong with choosing a simple plot, the lack of a strong and engaging screenplay becomes a major problem.

The opening portions move slowly, and the scenes involving the lead pair lack energy and emotional depth. The interval sequence attempts to create a dramatic twist, but the moment fails to generate the intended impact.

The climax and final portions are another disappointment. Instead of delivering a thrilling payoff, the ending feels stretched, with unnecessary scenes slowing down the proceedings.

Technical Aspects:

Jason Sanjay attempts to present a routine heist story in his own style, but the writing and execution fail to create the required impact.

Krishnan Vasant’s cinematography is average and does not offer much visual excitement. K. L. Praveen’s editing feels dated in several places, with distracting flickers and inconsistent visual choices.

S. Thaman’s music does not make much of an impact and fails to elevate the important sequences. The production values are adequate, although some of the green-screen work looks artificial on screen.

The Telugu dubbing is average.

Verdict:

Sigma is a below-par heist drama that struggles due to weak writing, flawed execution and underdeveloped characters. Sandeep Kishan puts in a sincere effort, while Sampath Raj performs well as the antagonist. However, the lack of freshness, emotional depth and engaging screenplay affects the film considerably. The repetitive second half and underwhelming climax further reduce its impact, making Sigma a disappointing watch.
