There are plenty of...atheist couples who have stayed together, happy and faithful for decades.
And, there are plenty of murders, rapists, and politicians who believe they are living happy, fullfilled lives. You make a point with no value.
The root of their problems was not that they didn't go to church often enough.
Nor does that sound like what the film is saying. "Going to church often enough" and having a fullfilling relationship with God are not any closer to the same thing than going to court a lot and living a lawful life.
The film seems to imply that one cannot really know the full meaning of love without taking and living by the messages found within the crucifixion and resurrection of Christ. If you are of the Christian faith and want to believe this, fine, but this message is a failure when you consider all of the non-religious, anti-religious, and differently religious intimate couples which have persevered and shown enduring love for each other throughout the relationship.
Again, you could turn this argument around and say "...if you want to believe that atheist attitudes will give you a good life, fine for you, but consider all of the religious - especially devout Christians - intimate couples which have persevered and shown enduring love for each other throughout their relationship...."
The fact is, a Christian person will believe their life is more fullfilled, more meaningful, and overall better if they live by their teachings. That fullfilled, meaningful existence, combined with the teachings of how to treat your spouse (which are all admirable) will, in fact and in deed, lead to a happier, stronger, longer lasting marriage of bliss. If an atheist or other religions can find that within their bounds of beliefs (or lack thereof), good for them. But, that won't make them better Christians, nor better Christian spouses.
Does Catherine return to her husband out of some "soul-searching" or any other religious experience. No, the action that final won her heart back? A $24,000 gift to her parents, by her husband. So basically, large amounts of money can fix a broken marriage.
I haven't seen the movie, so I can't speak to its message. However, I know I've given a great deal of money, my time and services, and goods over the decades of my life. The amount of money (or anything else) was never the strength of the gift - it was the selflessness of giving, and the boost (however large or small) it provided to the recipient.
If the movie implies that money can fix a broken marriage, then I would have to agree that it's a bad movie. If it demonstrates that someone overcame some self-centeredness and became the type of person able to give - even if it hurt the giver financially - and be a better human being, and the wife grew to love her husband even more because of who he became or returned to, well, that's a whole different message, isn't it?
