I loved it, but I've been waiting 9 years for someone to make a movie out of the book I've read at least 20 times (and to which the movie is very faithful.) It would be awesome if this movie/book caught on with a new generation. Yes, it's a cautionary tale, but since almost everyone in the developed world needs to learn the opposite lesson, it's also an inspiring one. It's definitely the kind of movie people will be talking about and debating for hours after they see it.
Here's the trailer.
