Name Change Ghotala!
I think the creators of the movie messed up big time with the title of this movie. They made a huge mistake by changing it from “Susanna’s Seven Husbands” to “7 Khoon Maaf” They should have stuck with the original title “Susanna’s Seven Husbands” which was apt for the plot and story flow (where 7th husband is God).
The audience is left confused about the 7th murder. But it’s a simple case of fallacy & thoughtlessness from whoever decided to call it “7 Khoon Maaf” The creators of the movie should either accept this 'grave' error or give an official statement about what the 7th crime\murder\sin was. (We paid for the movie and sat through it for 2+ hours so they owe us an explanation!).
Sorry for crying out that the emperor is wearing no clothes, but unless the movie makers explain otherwise, I think its just a name change ghotala.
