Sigma Movie Review: Jason Sanjay steps behind the camera for the first time with Sigma, a crime-heist drama starring Sundeep Kishan and Faria Abdullah. The film comes loaded with action, money, criminals, secret plans, and double-crosses, but does it have enough freshness to keep the audience hooked? Here’s our detailed review.
There is a certain curiosity attached to Sigma even before the story begins. The film marks Jason Sanjay’s first outing as a director, and expectations are naturally higher because of his family background. But once the lights go down, the surname outside the theatre matters far less than what appears on screen.
Unfortunately, Sigma takes a potentially entertaining heist setup and surrounds it with too many familiar ideas. The movie has scale, action, and an interesting central premise, but the screenplay often struggles to generate the tension that a crime thriller of this kind needs.
What Is Sigma About?
Sundeep Kishan plays Guru, a man who is struggling financially while trying to protect a library connected to his family and his mother’s memories. His financial troubles eventually pull him into a much bigger criminal world.
At the centre of the story is a huge stash of money hidden inside a heavily protected vault. The money becomes the target of several people, each with their own agenda.
The complicated trail involves criminals, a casino operation, drugs, a valuable key, and a pen drive. As Guru gets deeper into the mess, what initially appears to be a desperate attempt to solve his own problems turns into a dangerous game involving multiple players.
The setup has all the ingredients of a commercial heist entertainer. The problem is that the screenplay takes quite a while to turn those ingredients into genuine excitement.
Sundeep Kishan Is One of the Film’s Strongest Assets
Sundeep Kishan carries a substantial portion of the movie on his shoulders.
As Guru, he gets a character who moves between vulnerability, desperation, and action. The actor brings enough energy to the role, particularly when the story finally moves into its more physical portions.
However, the writing doesn’t always give Guru the depth needed to make him truly memorable. His motivations are understandable, but the screenplay could have explored them with greater emotional weight.
Several reviews have similarly highlighted Sundeep’s performance while pointing out that the writing limits what his character can ultimately achieve.
Faria Abdullah Adds Another Layer
Faria Abdullah plays Sam, an RJ whose storyline becomes connected with Guru.
Her character provides the film with a romantic and lighter thread amid all the crime and action. While the pairing brings some variety to the narrative, the relationship doesn’t always receive enough space to become an emotionally convincing part of the larger story.
The film has several characters and parallel tracks competing for attention, and that sometimes prevents individual relationships from making a lasting impact.
The Heist Sounds More Exciting Than It Feels
This is where Sigma faces its biggest challenge.
A good heist movie needs more than money, criminals, and a complicated plan. It needs anticipation. The audience should constantly wonder what will go wrong, who is betraying whom, and whether the characters will escape with what they came for.
Sigma has the basic ingredients, but the screenplay doesn’t consistently create that feeling of uncertainty.
The first half spends considerable time establishing Guru’s personal problems and introducing the characters. While this groundwork is necessary, the pacing can feel slow for a film marketed around a heist-action premise.
Once the movie moves further into the crime plot, the action becomes more prominent, but the story still carries several familiar genre beats.
The Interval Gives the Film a Much-Needed Push
One of the more effective portions comes around the interval.
The film finally finds some momentum through a major confrontation, giving the audience a stronger sense that the story is moving toward its central conflict.
This change in pace is important because the opening stretch takes its time getting there. Several reviews have also pointed to the interval/action portions as stronger moments in comparison with the slower setup.
Jason Sanjay’s Direction: Ambition Is Visible
For a debut filmmaker, Sigma certainly isn’t a small-scale experiment.
The film attempts to operate on a commercial canvas, bringing together crime, action, comedy, romance and a large-scale heist. The production values are visible on screen, and the movie occasionally delivers the visual scale expected from a theatrical action entertainer.
The bigger issue is the screenplay.
A strong visual presentation cannot completely compensate when the story becomes predictable. The central idea had enough potential for a more inventive thriller, but the narrative frequently settles for familiar territory instead of taking bigger creative risks.
Action Sequences Offer Some Relief
If there is one area where Sigma manages to periodically lift its energy, it is the action.
The movie has several physical confrontations, and some of the staging gives the film the commercial punch it needs. A multi-level parking-lot action sequence has been specifically noted as one of the more impressive stunt moments.
But the action works best when it is supporting the story. When the narrative itself isn’t generating enough suspense, additional fights cannot completely fill the gap.
Too Many Characters, Not Enough Depth
The film introduces a sizeable collection of characters connected to the criminal operation.
There are smugglers, drug dealers, casino operators, assassins, and other players, each bringing a separate piece to the larger puzzle.
On paper, this should make the story more unpredictable. In practice, some of these characters feel more functional than fully developed.
This is particularly noticeable because a heist movie depends heavily on character dynamics. When the audience understands what each person wants and what they are willing to risk, even a simple robbery can become gripping.
Sigma occasionally treats its characters as pieces that need to reach the next plot point rather than people whose choices naturally drive the story.
The Biggest Problem: Familiarity
The biggest weakness of Sigma isn’t that it lacks ideas. It is that too many of those ideas feel familiar.
The film brings together the usual ingredients — a huge amount of money, criminals chasing an object, secret plans, betrayals, police arriving after the action, and characters with hidden motives.
There is nothing inherently wrong with using established genre elements. The problem comes when the treatment doesn’t add enough surprise.
That is why the film can look bigger than it feels.
Music and Technical Presentation
The technical side of Sigma gives the movie a commercial polish.
The visuals help establish the larger crime world, while the action portions provide the required theatrical energy. Music by Thaman S also contributes to the film’s mass-oriented atmosphere.
But once again, the technical strengths cannot completely overcome the uneven writing.
A thriller ultimately lives or dies by its screenplay, and that is where Sigma doesn’t consistently deliver the tension its premise promises.
Is Sigma Worth Watching?
If you’re looking for a straightforward commercial crime-action film with a heist backdrop, Sigma has enough action and scale to offer a few entertaining moments.
However, viewers expecting a sharply written, unpredictable heist thriller may find the experience less satisfying.
The movie takes time to establish itself, and although the second half brings more action and movement, the screenplay remains tied to several familiar genre conventions.
The mixed critical response reflects that divide: some reviews have acknowledged the film’s scale, action, and Sundeep Kishan’s performance, while also pointing to its predictable writing and pacing issues.
Final Verdict
Sigma arrives with a promising premise and the curiosity surrounding a major directorial debut, but the film’s ambition is stronger than its screenplay.
Sundeep Kishan gives the movie the necessary energy, the action provides occasional bursts of excitement, and Jason Sanjay demonstrates an eye for scale. Yet the lack of freshness in the writing keeps the heist from becoming as tense or unpredictable as it could have been.
For Jason Sanjay, Sigma is an interesting first step — a film that shows ambition and commercial instincts, while also making it clear that the writing needs to be as inventive as the world being created on screen.
