I can't use the usual superlatives. I can't call it a "nice"/"good"/"great" movie.
It was heart wrenching and a punch to the gut.
I didn't/couldn't look away from a moment. And neither should anyone else, no matter the scene that is playing out and how hard it is to watch.
There are complaints that the movie is not accurate, because it has supposedly mixed things that never happened together. To those I would say:
1. The maker has said right at the beginning through a notice that they had to blend things together to make the movie.
2. Just because they have been blended and the timeline isn't shown accurately, DOES NOT mean that the things shown DID NOT happen. They happened, they have been witnessed and there have been news reports on them as well.
Kudos to Vivek Agnihotri and team for having the guts to make this movie.
