The '90s were a great time for in-your-face, inappropriate comedy films. These films epitomised tasteless humour. As time progressed, comedy became a little more refined, giving rise to the relatable slice-of-life comedies that took over at the turn of the millennium. Recently, we are getting quirkier humour, like in Mard Ko Dard Nahi Hota.
That is not to say that Bollywood is completely experimenting - we have films like Total Dhamaal that bring it to a screeching halt. But even these pale in comparison with Jhootha Kahin Ka, which actually falls on the side of regression.
