When a film is so over-the-top and the situations are so exaggerated, I tend to look for the spoof in it; the underlying comment; the cynicism. And of course, left to imagination, it ain't too difficult to find it either. But, Khichdi is so crass, that even when I laughed, I felt yucky inside. It's not the toilet-humor kind of crass. It's absolutely (hopefully-miles-away-from-reality) insensitive crass.
I guess, it's their way of saying nothing is worth taking seriously - neither deaths and funerals nor weddings; and certainly not respect for the older generation let alone each human. And while they are at it, as is in vogue these days, a potshot at the media and the education system too. As if darker the joke, harder were the writers laughing at how seriously we treat the issue in real life.
