Divya Delhi: John Abraham, Neeru Bajwa, and Manushi Chhillar star in Tehran. The movie streams on Zee5. Tehran is a good film by Arun Gopalan. It's more sincere than some of the big-screen espionage spectacles that have hit us like missiles. It fails to wow, not for lack of imagination or genuineness. Tehran is tough, determined, and real. After the 2012 Delhi attack on Israeli diplomats, Delhi officer Rajeev Kumar tried to stop Iranian terrorists in India. Rajiv's attempts to calm the girl's child after a bomb blast kills a street girl have an impact. Not much else seems up to the task. The building up to Rajeev's devastating promise to avenge the terrorist is great. Unfortunately, this plot point is resolved in just twenty minutes. John Abraham's tight, unconstitutional, quasi-diplomatic maneuvers remain. He played that position in The Diplomat recently and more effectively. Tehran loses its charm by sticking to its topic. Long portions with characters speaking Farsi are hard to follow since their words sound too evil. Naturally, everything feels real. But we never feel like we're in Rajeev Kumar's idealistic world. Many of the protagonist's goals match the film's. Rajeev wants to defend India from terrorism. This is as challenging as this ambitious film's goal. Tehran relies more on gut than facts due to its limited budget and resources. An overabundance of sincerity hinders this well-meaning project. John Abraham is a rugged nationalist, but performers who act like actors weaken his portrayal.
