If you want a good, thought-provoking movie about the war, go. Really, you should go. It will make you think and probably scare you more than you are already.
Especially those of you who are teaching college folks --- the Robert Redford character is excellent.
For a movie that mostly stars 6 people, it is extraordinary... and, it is hard to argue with that if three of the people are Tom Cruise, Merrill Streep and Robert Redford.
