Well, not one of the reviews or articles have failed to mention the religious theme, so they just didn’t do their homework, I guess. Even if the Christian message were not part of it, though, the fundamentals in this movie are so good, and I guarantee the idea of serving your spouse without selfishness is a new one to many people. It will, hopefully, be a turning point for many marriages.
I agree that the reviews have heavily mentioned it, but I guess some people don’t read reviews. Maybe they just look at the synopsis and go, who knows.
I do think young children would be bored though. I’d definitely recommend a babysitter.
