This movie is a good film, that's for sure. The actors perform brilliantly and the script is original and touching. However, all this is boring.
I guess people with an interest in the social aspect of one's life will find this very nice and good. For the parents (and children) who are on the same path as the character, should they choose to really understand the movie, it will be a learning experience that will save them from a lot of pain and anguish.
OK, the guy is a cowardly hypocrite that hides behind his intellectual aura tons of frustration and, surely enough, stupidity. The woman leaves a life of discomfort and maybe even fear, but lacks the courage to do anything about it. She cheats on the husband then leaves clues to it, so that the responsibility of the divorce would fall on him. The sons pick sides based on age, both mimicking behaviour that they don't understand yet, and thus making fools of themselves. Very weird and socially tense situations, but that's it. After the first half an hour you know everything there is to know, only the awkward situations remain, in a hostile, not humorous manner.
The ending is as devoid of resolution as the entire content. The problems are there, you know what, where, when and how, but there is no solution. In the end, the film is nothing but a portrait, you either like it or you don't.
