Overall worth watching.
First drags a little bit, but the second half is gripping. They should've focused less on the character building of the protagonist and more on details of the train burning incident. Also, the background track of Jai Rajaram seemed forced at the climax.
But I liked is that the film brings forward the cause and politics that went resulted in that disaster, which the new generation is not aware of. The media always focused on the riots that followed, but didn't give justice to the victims of the train burning.
