The movie inspite of being made by a right leaning director puts forward all aspects of the conspiracy. The movie repeatedly points out nobody wants the truth, everyone just want their propaganda.Ultimately it doesn't conclusively say as who murdered Shastriji, but leaves audiences with intriguing questions on Indian history. It fairs poorly on the background score but is gripping till the end.
It will at least educate you about a certain Mitrokhin who could have been a bigger celebrity than Assange and Snowden. ..
Last but not the least NDTV Scroll i am convinced that you deliberately gave it bad reviews because as the movie says it doesn't support your version of truth...
