Not a movie to watch when you're looking for an upbeat night, but it might be the right movie to watch anyway. 

It's based on a book by a newspaper columnist played by Owen Wilson (the 'Me' in Marley and Me) and describes him and his wife starting their lives out together, through having kids, all the while accompanied by their dog Marley, a notoriously misbehaved dog.

Watching this movie made me think back to Old Yeller.  Definitely a heartfelt movie and maybe it'll occupy a similar place in people's minds in decades to come.
