I have no idea how accurate it is because I am not at all familiar with the historical characters.
What I do know is that I enjoyed watching the film. Brilliant performances by all (I for one never expected Ranveer Singh to be capable of such a performance). The dialogues were pretty good as well and I will be watching this again.
That said, the film could’ve been better with fewer songs and less use of that screen splicing technique nonsense that seems to be catching up in Bollywood (The technicians clearly don’t know how to get it right, just yet).
The plot would be served a bit better if some bits were put in about the situation in Bundelkhand after Mastani’s departure. I mean… she is the king’s daughter. It did seem an oversight not to include a single sequence showing the concern of the king about his daughter’s plight/general wellbeing.
