The thing is few of both negative and positive reviews are copy pasted here. Can watch the movie for mahabharat scenes and Amitab action. Rest all the things are not so good. The scenes and fights were dragged so much and there were so many unnecessary characters. More than the hero other characters were highlighted. To say frankly, the hero's character in the movie didn't feel like a hero but a comedian.
So what I liked is, how the movie has started and how the characters are related to mythology. It gives a message the selfishness of humans will destroy humans some day. We exploit the nature and we have to face consequences in future. And when we are selfish and greed someone can rule us easily. It's only when we mend our ways our future will be secured.
I dearly wish I could see Kalki next movie
