^Never saw the movie, but I read the book a couple of years ago. I don't recall if that Krishna story was in the book. I liked some aspects of the book, but overall I was a bit disappointed in it. That's just me, though.
There wasn't anything particularly special about the story itself, but the film was very well done, imho. On the other hand, I liked the element of.faith/religion and a young man's struggle to survive in the middle of the ocean.
