Sigma movie review: Jason Sanjay’s debut lacks script depth

Jason Sanjay's directorial debut Sigma follows Guru, a treasure hunter and radio host played by Sundeep Kishan seeking revenge against a syndicate boss.

Reviewers praised Sundeep Kishan's energetic performance, screen presence, and physical commitment in action sequences.

Critics noted the film suffered from a thin screenplay, generic villains, poor musical scoring by S Thaman, and disorienting rapid editing.
