This is a sc-fi master piece that the more time you watch it you realize how much a genius the director was. You must watch the bonus features to get a full understanding of how clever the director was and imginative the story
I see no way to watch this movie and not be moved with a greater appreciation for how combat must feel. There are other great war movies but none will stick with you as this one does but for the exception of "Band of Brothers series" (also by Tom Hanks). Kinda sad that Tom is recently showing his true island hopping self, damn, still good movies though.
First, if you have never read the books, do it now. (drop everything in your entire pathetis life and start reading) The books are < the movies however the movie adds some clever elements that never take away from the original prose as tolkien wrote.
