I read the book this weekend, having missed the movie at the box office. I intend to get the video when it comes out.

A very dismal tale. Only the dimmest glimmer of hope at the end. Very sobering reminder that no matter what you do, eventually you are going to die anyways. At some point, the perspective of existenece is reduced to just what can be done today, for today. That was more or less what I came away from the story with.
