Yes, finally, after the studio delayed the release date of the DVD a few times, and already fuming because it never showed in any theater in my area! I read the book a few months back, and was thoroughly impressed. I wanted to see how the movie compared to the book - in general, I've found that movie adaptations of books are stinking, pale imitations.
This movie actually captured the "flavor" of the book pretty darned well! The movie is a bleak journey, but one well worth taking. See this one, you won't regret it.
