‘Sigma’ Movie Review

Initial reviews indicate that Sigma excels in technical scope but stumbles in screenplay precision. Critics generally praise the scale of the production, highlighting well-designed set pieces, slick cinematography, and lead actor Sundeep Kishan’s committed performance. The action set pieces, including sequences set in casino locations and complex logistics setups showcase Jason Sanjay’s intent to deliver a mainstream commercial spectacle with strong visual appeal.

However, the major point of criticism across multiple reviews lies in the script's reliance on predictable tropes and a lack of narrative depth. Film analysts note that while the core concept promises a sharp heist thriller, the execution suffers from pacing issues, flat dialogue, and an overstretched second half that dilutes the tension. Overall, reviews conclude that Sanjay demonstrates technical competence and ambition behind the camera, but the film ultimately feels like a missed opportunity due to weak writing.

India Today: "Sigma ultimately lacks conviction, invention and a clear sense of direction. For Jason Sanjay, it is a disappointing debut — a film that has all the ingredients for a heist, but somehow forgets to make the heist exciting."

Times of India: " Most of the buzz around Sigma has been because the film marks the directorial debut of Vijay's son, Jason Sanjay. But 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."

Moneycontrol: "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. If you are the kind of viewer who likes a template kind of action film, then you can go for Sigma."

Only Kollywood: "Overall, Sigma is a straightforward commercial action entertainer built around a large-scale heist premise. Sundeep Kishan leads the film with a sincere performance, while the casino setting, action portions and technical presentation add to its appeal. Jason Sanjay’s debut shows ambition and an interest in delivering a mainstream theatrical experience. With its familiar storytelling and accessible treatment, Sigma offers an uncomplicated action ride for audiences looking for a commercial entertainer." ‘Sigma’ Trailer: Vijay’s Son Jason Sanjay’s Film Promises a Thrilling Heist Adventure.
