Contrary to most Christian movies, you do NOT have to be Christian to enjoy this film.
Christian movies often seem to receive low ratings. I understand low ratings for many of these films because the Christian message is very ham-fisted and is probably not enjoyed by people who are not open to Christianity. However, this is not one of those movies, and that helps make this one of the best Christian films I've ever seen.
This is a movie about struggles within military families, and people who have family members or friends in the military will probably relate very well to these issues. I never shed a tear, but I was fighting them back for about half of the movie. It is paced very well to spread the emotional scenes throughout the movie. As each person attempts to overcome their struggles, only one of these people (a relatively minor character) appears to overcome their struggle through faith. All of the other major and minor characters may be intended by the screenwriter to have God working in the background, but at face value their struggles are all overcome by people helping each other. Despite the main character being a chaplain, the theme of the movie is really that people handle difficult emotions better when they ask others for help.
My biggest complaint is that the dialogue seems quite bland and cliched. It's never obviously bad dialogue, but it's also never particularly inspired. However, the actors still perform quite well, which is not standard for a Christian movie. And again, the overall story is still quite good despite the dialogue.
