The Plot
I was really surprised at the subject matter of this particular movie, since it showed such a selfish hedonistic guy, using several women. Usually in Bollywood movies, you don't see a movie that is only about mistreatment of females this way.
But one suggestion, it would have been totally righteous if at the end Ranbir wound up alone, because karmically speaking he deserved it. I know he tried to atone for it, but just as he left those women in the lurch, so should he be. They didn't win him over, so why should he have the one he loves?
Food for thought.
