In addition to being the same age as the main characters (I'm turning 40 this year and my wife will be turning 40 next year), we've faced a lot of the same situations. The oldest daughter (Maude Apatow) reminded us a lot of our oldest daughter, especially when it came to some of the conversations (minus the swearing) she had with her dad. And, what married couple hasn't had relationship stress caused by money? Not to mention I'm not convinced we wouldn't act any differently if my wife were to find out she was pregnant again, like Mann's character in the film.
Another thing I found I liked about this movie was the way it avoided being as predictable as other films in this genre. There were a variety of twists and turns I honestly wasn't expecting and there were times when I did find myself wondering if they would find a way to make their marriage work or the film would end with them realizing they would be happier if they were divorced.
One thing that really surprised me about this movie was the clever way it managed to have scenes (especially when they were fighting) that were both dramatic and a bit funny at the same time. I would find myself laughing then, when I realized just how serious the situation was and how close they were to having their marriage fail as a result, I would feel guilty. It was a unique experience to say the least.
I was a bit undecided about the ending of this film, mostly because it's not one of those feel-good endings that solves everyone's problems and, instead, the characters still faced quite a bit of uncertainty. While part of me wanted to see more closure, I also had to admit I liked the fact the writers decided not to make things easy on the characters by having some sort of cliche miracle and, as a result of that, do feel I enjoyed it overall.
