Nikhil Dash’s review published on Letterboxd:
Shoojit Sircar just can't stop making great films. Sardar Udham is far from any regular biopic or period film from the mainstream. It's less about documenting Shaheed Udham Singh's life and more about understanding his ideology and portraying the political turmoil and anger, post the Jallianwala Bagh massacre. It's so rare to see a Hindi film that's honest about Bhagat Singh's Marxist ideologies and isn't afraid of talking about HSRA's contribution to the Indian freedom struggle. Very much like Raoul Peck's The Young Karl Marx, Shoojit's film manifests itself in the idea of total revolution which serves as it's core philosophy, instead of being a Wikipedia page adaptation of the real life persona. Even the time jumps here are reminiscent to Peck's film.
Apart from the direction, Avik Mukhopadhayay's cinematography stands out exceptionally well. I'm happy to see Vicky Kaushal back in a bold, unconventional film after quite a while. There is a lot of violence here, and justifiably so. Shoojit persists on making the audience understand the brutality of imperialism and the need for revolt, which is undoubtedly relevant considering the recent violence on protesting students and farmers.
