I haven't seen movie so insightful, thoughtful, making simple yet clear impression and detailed, through brutal true events, thoughtprocess of any person. The movie is justifying full marks to the symbolic representation of Sahid Ram Mahommad Singh Azad (Sardar Udham). Each and every picturization on every part of Udham Singh's life events starting from his activisom with Bhagat Singh, assasination of O'dyer in his own country and hometown, brutal interrogation, 40-45 long efforts (10-12 hours of actual) of saving lives of almost dead survivours of jaliwala bagh tragedy (painful watching it). And this experience of an orphan young man avenging it after 20 long years, after being satisfied that the person responsible for killing of thousand innocent people having no regret, rather taking pride of such an evil act.
Using name "Ram Mahommad Singh Azad" and taking oath of his own choice book "Heer" in court trial is representing his Ideology.
