A little while ago I rented Marley and Me. I had read and enjoyed the book and so knew it was more than a 'dog movie'.
What I hadn't expected was such a lovely, realistic and positive depiction of a marriage through many years. Basically it's the story of a couple as they move from being happy-go-lucky newly married, to stressed new parents and then a mature middle age couple. And all their experiences are punctuated by a crazy mischievous dog.
This movie doesn't gloss over the messiness of life, and the couple defiantly have their problems. It's a movie about finding that their life didn't turn out the way they wanted, but maybe this was better than they expected.
Even when the world around them says they'd be happier if they broke up (and they sometimes wonder it themselves), But they are committed to each other and their family. They decide that things will happen, but they can get through them if they meet them together.
Or as Owen Wilson's character says; "Mend it, don't end it"
