I put off watching this movie for several years because it just didn't sound like something I'd like, and there have been so many badly-done Vietnam-remembrance movies. I didn't want to see one of my favorite actors (Don Johnson) in one. When the movie began I had no idea that Don's son Jesse plays him as a young soldier, and couldn't figure out where they'd found someone who looks EXACTLY like he did in his 20's to play his younger self!! Then the words "Jesse Johnson" flashed across the screen and I about dropped my glass of iced tea --Jesse's grown up! How time flies. So I settled in to watch with a critical eye. The younger Johnson played his part flawlessly, never over-acting, but very believable in very difficult circumstances. The movie shields the viewer from the truth quite well, I couldn't figure out what actually happened at all until it is revealed.
Don is characteristically excellent, but then I am admittedly biased. To me Mr. Johnson gets into the heart of his characters like few other American actors today. Through his soulful handling of the difficult character he plays the movie's message comes through loud and clear.
It would have been a stronger movie if the character playing Marcy had been stronger. Although many of us may have skeletons in the closet, she comes across as a bit of a screaming mimi and "why me?" character. If these characters had a good marriage before (reportedly, we don't see enough to judge IMHO), then her first reaction shouldn't have been to be defensive and and offensive by turns to her husband. It would have been better if we had seen a Marcy worth fighting for, as Ben Tyson claims that "his family is everything," and he struggles to put them first all the while he is fighting what is happening. There is a scene where you finally understand why & how important his family is to him, but to me it comes waaaaaay too late in the movie. A few more close-family scenes in the first hour, and a wife less shallow & selfish, would have gone further to me to establish what Ben Tyson actually had, and would have upped my rating by at least one point. This guy is fighting the battle of his life and trying to save his marriage at the same time, and you want to ask him why he doesn't just tell her off at some point. His son's character has more depth and is very believable.
All in all, an excellent movie worth a few repeat watches. It definitely leaves you with a few deep thoughts at the end, not the least of which is, "Who is Thucydides, anyway? Must check him out...."
