Just so you know, I watched this days ago and have been struggling with it.
Giving it three stars is something of a stretch for me.
It's a movie about the life of the dog, Marley, and his effect on his family.
The basis of the movie is that the dog dad, played by Owen Wilson, starts writing a newspaper column about his life... which is mostly about Marley.
So, the movie kind of feels like you're reading his columns.
It's a nice story and very well acted by Wilson and co-star Jennifer Aniston, but it's just not that great. I think if I'd been an avid reader of the columns, I may have been disappointed by the movie. Not a big surprise.
All in all, it's ok for a Sunday afternoon... for you and the kids.
