Sigma Review: Jason Sanjay's Tamil Action Debut

Our hero is a treasure hunter of the "leap first, calculate never" variety. He's chasing something valuable - the specifics matter less than the chase itself - and standing between him and payday is a gauntlet of deadly traps, a rotating cast of treacherous allies, and at least one person who definitely should not be trusted with a map. What follows is a cat-and-mouse game where the cat and the mouse keep swapping places. The screenplay keeps the plot machinery churning, tossing in double-crosses at regular intervals to keep the audience guessing who's actually on whose side. Sometimes it works beautifully. Sometimes it's a little too clever for its own good.

Let's start with the obvious: Sundeep Kishan is having a blast. His treasure hunter is all instinct and smirk, a guy who survives on nerve and sheer audacity rather than any kind of actual plan. It's the kind of performance that could easily tip into annoying, but Kishan keeps it grounded with a scruffy charisma that makes you want to see him wriggle out of the next impossible situation. Faria Abdullah, playing RJ Sam, brings a different energy entirely - sharper, more guarded, and the scenes between the two of them crackle with an easy back-and-forth that the film could have used more of.

Jason Sanjay directs like a man who grew up on a steady diet of globe-trotting adventure films and wanted to make his own. The set pieces are staged with real enthusiasm - there's a trap sequence in the first act that's genuinely tense, and a mid-film chase that makes great use of narrow corridors and bad decisions. Raju Sundaram and Sampath Raj round out the supporting cast with the kind of lived-in presence that makes the world feel a little bigger than the script strictly requires. Shiv Panditt, Anbu Thasan, Yog Jappie, and Magalakshmi Sudrasanan all get moments to shine, though a few of them deserved more screen time than they got.

The problems start when the film mistakes complication for depth. At 147 minutes, Sigma has room to breathe, but it doesn't always know what to do with that room. The middle section sags under the weight of too many characters with too many shifting loyalties, and the pacing stumbles just when it should be sprinting toward the finish line. There's also the nagging sense that the film is holding back - playing it safe with a formula when it could have pushed harder into genuinely surprising territory. The TMDb rating sitting at 0/10 right now is meaningless this early; ignore it. Real audiences will decide what this one's worth.

What saves Sigma from being forgettable is the sheer commitment of its cast and the confidence of its direction. Sanjay knows how to frame an action beat, and he knows how to let his actors breathe when the script gives them something to work with. The film has a pulse.

Pros:

• Sundeep Kishan is magnetic as the reckless treasure hunter - a star turn
• Faria Abdullah's RJ Sam brings sharp, welcome energy to every scene
• The action set pieces are staged with real tension and creativity
• Jason Sanjay's direction shows genuine confidence for a filmmaker at this stage
• The supporting cast adds texture to a fairly by-the-numbers premise

Cons:

• The 147-minute runtime feels every bit of it, especially in the middle
• Too many shifting loyalties muddy the plot rather than deepening it
• The screenplay plays it safe when it should swing for the fences
• Some supporting characters get lost in the shuffle

Sigma isn't the kind of film that reinvents the treasure-hunt genre - it's the kind that reminds you why the genre endures. Sundeep Kishan's star power, Faria Abdullah's sharp presence, and Jason Sanjay's confident direction make this a ride worth taking, even if the engine sputters a bit in the middle. It's a good time at the movies, not a great one, and for a director's early outing in Tamil cinema, that's a promising sign of things to come. Catch it on the big screen if you can - the trap sequences play better with a crowd.
