I thoroughly enjoyed the thriller almost at the level of Andhadun except that mental illness is showed in judgemental hai kya which also has a social angle. Also its very innovative and experimental in its story. So you won't find it like a regular bollywood movie.
I dont like really dark movies so this movie didn't go to an uncomfortable darkness level. There was some good comic punches in between which really lightens the feeling.
The movie held me tightly for 1 hour 57 minutes.
There can be some small issues in the movie like some part of stories like police investigation could be more interesting.
It might not be the best movies ever made but surely one amongst them.
Its a must watch even if you watch selected 3-4 movies in a year like me.
