Well... I guess most people based their views on through present day lens. I guess the concept of multiple wives didn’t really sit down with people and so Kashi automatically is the wronged party. Also the second half of the movie we saw more of Kashi always tryna do the right thing, and overshadowing Mastani, her courage and sacrifice was highlighted overtaking Mastani’s warrior persona. Whether that was purposely written like that or the DP failed while PC absolutely ate up that latter half is debatable. I know many people left that movie in awe of Kashi.
Also the whole mastani’s persona was never as impactful, at times it looked robotic performance wise, although she looked stunning.
