Saving Private Ryan Review
I have to say, I was really suprised by this movie. I had heard it was supposed to be really violent, but when I actually watched it (at age 12) it wasn't that disturbing at all.
The movie it self has a lot of positive messages, and it is really realistic. I heard that cases of stress among former WW2 veterans increased dramatically after they showed it in theaters. It does get a little old at times, as some war movies do, but the opening scene and ending scene were both superb.
To sum it up, I'd have to say 12+, though maybe with adult supervision, and 14+ If you're a bit squeamish.
