I was absolutely WOWED by the effects and story line. I took my kids (age 11, 13, 17) and they were astounded. My daughter, the youngest, wasn't shocked by the content as kids are now more sensitized to on-screen horror/sci-fi/harsh dramatical content etc, and was really into the story-line and action more than anything.
I give it a 9/10 rating just because I can! Love it!
