If this movie was dedicated to the director's mother because she was a homemaker, then this was an insult to the poor woman.
Even when telling women that they're not *just* housewives, they are telling women that you have inherently less value if you're only *just* housewives. Because here, to be of any value, the women had to be undercover agents and almost literally be like a goddess. Pretty big shoes to fill, eh? The world, it seems, is busy telling women how they're not enough no matter what she chooses. If she chooses to work outside of the home, then she is not a good mother and wife. If she chooses not to work outside and be a homemaker, then she is not enough anyway according to the feminist landscape of today.
Also, if the mother-in-law wasn't busy lamenting her fate as a housewife and dreaming of dishoom-dishoom, she might have raised a better son. Not saying that the father-in-law didn't have any responsibilities but he was hardly there in the movie.
