Critic Consensus

Critical consensus on Sigma is largely negative, with reviewers finding the film a formulaic and outdated entry in the heist-action genre. The most common criticism across reviews is the weak, unoriginal screenplay that fails to generate the tension, ingenuity, or emotional investment the genre demands. A few critics acknowledged flashes of promise and noted the presence of grand production values and elaborate plotting, but agreed these elements are squandered by poor characterisation and an unfocused narrative. The film's failure to push beyond genre conventions was a particular disappointment given its debut context.

Akshay Kumar· Cinema Express
5.0
“Sigma is a curious amalgamation of everything and nothing. Yet, for all its elaborate plotting and big action set-pieces, Jason Sanjay's directorial debut rarely settles on what kind of film it wants to be. The film is a classic case of how ideas can only take a film so far.”

5.0
“Even for a debut effort, the film comes across as just a standard issue crime thriller that has the elements that we find in films of this genre but without strong writing that is needed to bring them all together in a satisfactory manner. What we don't get is the tension that we should be feeling. We never care for Guru and his troubles, for his romance with Sam, for the sentiment the library holds for him, for the plotting of Reddy, Vincent, Sarangi and Y.”

5.0
“Sigma has all the makings of a commercial heist-action movie, but its formulaic treatment prevents the premise from making much of an impression. The first half doesn't have the action expected of the genre, while the second half has more action but doesn't entirely escape the limitations of the screenplay.”

“Sigma is a below-par heist drama that fails to make much of an impact. Sundeep Kishan puts in a sincere effort, but poor writing, flawed direction, and underdeveloped characters work against the film. With little emotional depth and a stretched runtime, Sigma eventually turns into a disappointing watch.”

Janani K.· India Today
4.0
“Sigma is painfully outdated and stacked with one stale idea after another, none of which does justice to either the heist or drama elements. A heist film needs ingenuity, tension and the thrill of watching a seemingly impossible plan come together, but Jason Sanjay's drama is weighed down by familiar ideas that do little for the genre or the audience.”

“Sigma is old, outdated and it offers nothing new. Sundeep Kishan and Jason Sanjay delivers a film that will appeal to none. The story is old fashioned and outdated, and despite grand production values, the film lacks any memorable performances or emotional connection.”

“Sigma has the ingredients for a kickass heist thriller, but Jason Sanjay's debut gets hopelessly lost in its lazy writing and bland execution. The screenplay keeps introducing characters, relationships, skills and plot twists precisely when it needs them, without doing the groundwork to make any of them feel convincing.”

3.0
“Sigma is a heist film that forgets to steal your attention. The core problem with Sigma is that the screenplay does not understand the mechanics of the genre it is operating in, with the plan presented but not stress-tested and complications introduced but not explored.”

3.0
“Sigma is a surprisingly awkward launchpad for Jason Sanjay, the son of a massive star like Vijay. It is hard to believe a young debut director has come up with something this outdated, routine, and exhausting.”

3.0
“Sigma is a patience testing thriller let down by weak writing, poor characterisation and an unnecessarily stretched narrative. What could have been an engaging money-heist thriller instead turns into a tedious watch.”

Not rated
“For a debut backed by a recognised production house, I could not help wondering why Jason chose to play safe rather than push the boundaries of the conventional heist-action drama. There are flashes of promise, but a fresher storyline would have announced his arrival with greater confidence.”
