After watching the movie, I felt that the writer and director purposely moved away from the original story of the gods to create an "original" story that depicts families in today's societies - where its members turn away from each other because of power, money or other selfish desires. I may be wrong on this.
I agree that the actors could have done better to easily stir emotions of viewers. But I believe that if I a person can relate to the story or values that the movie wants to teach, it can indeed bring about the intended effect. The themes were obviously laid out anyway - revenge, envy, fatherly love and strength of human spirit.
Overall, I think the movie is a good action and sci-fi treat rather than a mythology on-screen adaptation. It's worth watching, but will not leave a lasting impression though.
