This is a movie about a time in your life when your fundamental believes are challenged.
Setting is a typical affluent, suburban setting: well do family, nice house, nice area, nice kids in short everything nice. Suddenly husband disappears seemingly with his Swedish secretary and fall falls apart, at least it seems to be. Mother takes up drinking and her equally drinking neighbour, daughter drops out of school, take elderly lover, the other gets pregnant and the other one dances her into ill-health. There are horrible scenes; one feels the hurt, the confusion, the frustration, the anger, wanting to lash out. But there is more: there is the memory of good times, the knowledge what is right and good, the love for each other but all is cover by anger. Nevertheless the anger helps to get over the initial shock, the feeling of betrayal. But anger has to stop because one gets lost in self-pity and that leads nowhere. And it does and step by step all characters get back on track, even stronger than before. When the final shock occurs, but here they have already made it and cope with it.
The movie is nicely done, well played, of course in many ways very American, but there is a great message. It is an inspiration. I liked very much Joan Allen. With Kevin Costner I always had and properly will have my problems. But he does not too badly here.
Anger changes situation and people, it might be necessary for a time but it should never be the long-term solution. So enjoy it!!!
