It received a standing ovation during its world premiere at the 2022 Cannes Film Festival .

The film received a polarizing yet generally respectful reception from critics and high praise from the public:

, released in July 2022, is a biographical drama that serves as both a cinematic tribute and a rallying cry for justice for the ISRO scientist Nambi Narayanan . Directed by, written by, and starring R. Madhavan , the film highlights Narayanan’s groundbreaking work in cryogenic engine technology and his subsequent false arrest in 1994 on espionage charges. Core Story & Narrative Structure

A significant portion of the film focuses on the 1994 spy scandal that derailed his career. It depicts the harrowing physical torture and public humiliation Narayanan and his family endured before his eventual exoneration.

While Madhavan’s transformative performance was widely lauded as a "one-man army" show, some critics at The Indian Express and Lehren found the writing "stodgy" and the first half overly technical.

The story is framed as a long-form interview conducted by Shah Rukh Khan (Hindi/English versions) or Suriya (Tamil version), which transitions into the historical flashbacks. Critical & Industry Reception
