Movies like these rarely come in Bollywood and I really applaud their marketing tactics. They released the film on the day of announcement of the film being sent for Oscars, which was a good gamble. There's no way a lot of people who have seen this movie, and made it a success, would have watched it otherwise.
There is a much needed class and subtlety in this movie. I specially like the suggestion they made with the shopping mall scene. Nothing was said but a lot was done! Something that is a big rarity in Bollywood. The movie tackles a serious, controversial and conversation-sparking topic with extreme good care. They managed to make people laugh while making them aware about a lot of things going on in the country.
The director needs to be applauded for this one. He has a very firm grasp on Indian culture and it's nuances. He chooses to portray it really well. No unnecessary dramatization was done. Minimalistic approach of the director makes the movie appealing. The cinematography is brilliant and refreshing.
The screenplay is smooth and never feels abrupt nor slows down to boring at any point. The film has been edited well enough to make it an engaging 1-hour-46-minutes experience.
When you have Rajkummar Rao in the movie, you do not doubt the acting skills but even he has bested himself with this one! The typical character nuances, speech, diction, blinking of eye, he perfected literally everything!
Final verdict: A MUST WATCH. I really hope people would make this a bigger success (chances are scarce) so that the producers would start shifting their focus from unbearably stupid movies like Judwa 2 to classy satirical movies like this!
