Honestly, It is not as great as Hirani sir's other movies...
In his other movies, in every scene we see a kind of satire that shows the "wrongness" ( if that is a word ) of a certain idea...
But in Dunki, only in the second half of the movie, does he use "visible" satire and dissing of Dunki routes and visa systems....In the first half, the movie it is just lingering in the background like a leper...
Still, the movie is not that bad...He did an amazing job at addressing an often overlooked issue..So yes, it is a good film, but could've been better...
