This film has deeply affected me. The first time I saw it I had tears pouring down my face throughout. The second time I found myself really getting into it. Sure, you know what it's about from the other reviews. We ask ourselves why Frank isn't content with life. Most of us would feel closer to Joe, but Penn enables us to sympathise with this wretched character of Frank. He's not a nice guy. Myself; I am happy that this film is not necessarily a period piece. It takes a while for you to understand in what context the film is set. What makes this movie so good is that is underlining message remains ambiguous. This is certainly a film that will stand the test of time. It's not about the nation of America during the 70's. It's about the relationship of two brothers, and one just so happens to have come back from Vietnam. It could have been set in 2003 and the underlying message would remain the same. The talent of Penn is in that he never once blames Frank's actions on the Vietnam War. He was a bad kid before the War. I urge everyone to see this movie. You will either sympathise with the characters and understand the underlying message or you will not. I also urge you to open your mind before you see the movie, and if you don't understand it. Think about it for a while longer.
