Lies ! Lies ! Lies ! This was a good fictional movie *but* it showed India as a huge crazy place where people ate snakes and monkey brains !!! India's history and culture is nothing like China's, I think the film makers tried to mix the Indian culture with the chinese history.
Also it showed a beloved hindu goddess, Kali as some demoness of hell when in reality, she is considered to be very kind-hearted goddess and actually, the wife of Lord Shiva. 'Kali' is the most furious form of Goddess Parvati which she took herself to kill one of most dangerous demons of all time, Raktabija. 'Goddess Durga' is also her form which she took to kill a demon, Mahishasura.
To impress the goddess Parvati/'Kali'/Durga, some small cults used to sacrifice the heads of male humans in ancient India but they were selfish, stupid and illiterate ones, they used dark science and black magic to get some special powers over nature...still, very few people exist and get active during 10 special days of worshipping Goddess Durga but they don't get to perform any sacrifices of humans, they take some sheeps or goats for that. Let me make it clear, god cannot be happy with such kind of acts, ask the devotees ISKCON community for more knowledge, yes ! the Hare Krishna ones. They will tell you better if you want to know about 'True Hinduism'.
Once, there was a man who was a true-worshipper of 'Lord Vishnu/Ram/Krishna' and he got caught by those stupid worshippers of 'Kali' for the sacrifice. Goddess Kali showed herself there from her idol only to chop off the heads of her stupid worshippers.
God is one who can take various forms according to the needs and wants of true-worshippers having pure intentions. He/She can be our father/our mother or our brother/sister/friend. We use chairs, tables, beds, pencils, etc., all can come from same wood.
