Watching Saving Private Ryan will end your childhood, Oog.
Are you ready to grow up this soon?
Just kidding, but it has a lot of impact of hard reality of what lies in store for young men only 6 years older than you... quite realistically depicted very bad things that happens to young soldiers on a battlefield even though the actor's ages makes it look like it's only about older guys.
It changed me and I will never face a battlefield.
It might not be too bad on a TV screen, though. But at your age I would not recommend seeing it at a movie theater with full volume surround sound.
You can save the movie for another time when you are ready to face your mortality.
If you simply must see a war movie... rent "Master and Commander."
http://www.apple.com/trailers/fox/master_and_commander/Best all male casted movie war movie I have ever seen. A guy I used to date read all of the Aubrey-Maturin books by Patrick O'Brian even though he was a Col. in the US Army; he took me to see this movie.
Master and Commander is a historical naval novel by Patrick O'Brian. First published in 1970 it is first in the Aubrey-Maturin series of stories of Captain Jack Aubrey and the naval surgeon Stephen Maturin.
TIGERESS
PS: I had to walk out of "Born on the Fourth of July" crying my eyes out.
Makes me weep to even recall it.
