As someone who read the autobiography, I would understand why the low rating. This film is not for everyone. The time jump can't be really confusing.
My only disappoinment is why Kangana did not developed Madam Indira character properly from the get-go. There is a lot direct inspiration could been picked up from the book. For instance, the war in East Pakistan was a pivotal moment in her career as the PM, but, it dropped dead so fast. I wish someone could pickup this film as a full length series.
Good effort but such a waste.
