If you choose to read the book, which I'd recommend to you, you might change your mind about the movie. I can't judge it without actually seeing it, but everything I've read suggests it's not a well thought out adaptation. I can see that youth dystopian stories like The Hunger Games are hot right now, but that's not the sort of story that the book presents. The primary question that's presented in the book is, how much should you give up to create a "utopian" society? Jonas' community is very ideal and has accomplished many things, but it's only when he becomes the Giver's apprentice that he gets an opportunity to understand what the cost of that stability is.
