It is a good movie.I personally loved.
People are pointing out the slow pace. Well that's the point of the movie. The human greed and the fast pace culture we built around it has doomed the earth entirely.
Do enjoy the masala movies nothing wrong with that,but at times please spend some time in such good movies as well. They'll act as a detox.
Kudos to the movie team for sticking to the humbleness without going for flashy stuff
