As a Bangladeshi, I have to give 2 out of 5.
What is shown in the movie is not the actual scene in Bangladesh. You cannot just recognize the surroundings only by CNG rickshaw.
Most importantly, the worst part was, the accent was like Indian Bengali or Bihari. Actual Bangladeshi people doesn't talk like that.
Another minus point was, not every home doesn't listen Hindi song all the time.
Another down part was presenting law enforcement agencies. They are not same as the real one except Army.
And the last part was, the reaction of people and news reporter here is totally different from others than any other country.
Conclusion is, proper scene was not reflected here.
If you are not Bangladeshi, then you won't realize them.
