Spoiler alert:
To understand this better you have to have a little knowledge about Kalki, puranas vedas and scriptures from buddhism claim that there will be an avatar called Kalki who comes in a white horse, dressed in White, defeats the Kali and starts SatyaYug at the end of Kali Yug. So here the one who claims to be Kalki is not the actual Kalki but he is Kali i.e the destroyer, Satya is the actual Kalki and he deafets his arishadvargas and starts SatyaYug, but the humans just like how they killed Jesus and Basavanna kills the actual god and worships the destroyer thereby bringing doom on themselves. The ones who have no idea of the above concept would endup feeling that this movie only is intended to educate audience and promote Prajakeeya.
I def liked the movie
