I don't know why it has such a low rating on IMDb. It deserves 7.5 and above. There are some drawbacks like convenient storytelling but it is easily overshadowed by powerful performances. The larger cause that it serves i.e. depicting life in a dystopian future is remarkable.
The characters are strong, powered by excellent acting and cinematography which ingeniously captures the grief, the evil, the fragility, the vulnerability of the characters.
I believe one must watch it even though it may come off as an exaggerated version of current Indian dynamics, as it has elements that makes you empathise with characters. It is a little uncomfortable to watch yet it adheres to the cause which makes it binge worthy.
