This film, as I see it, is a slightly absurd view of the world through the selective gaze of two young persons in love. Although this film is far more realistic that the later films by Roy Andersson, it still has an absurd feeling, especially in the final part, but also before. But as a young person this was, at least for me, the way the surrounding appeared to be. You saw things, heard things, people cried and did things for reasons which you did not fully grasped or cared about. The unhealthiness of your family and every-day had become like a too well-known background noise which you only got aware of later in life. Therefore, all the partially touched-upon subjects in this film which never are fully resolved or explained are a strength not a weakness, I think.
The film is also political. The class society in welfare Sweden is shown. It is not the upper-class vs. servant class, but rather it is the "quest" for prestige of the every-day among working and middle class that is portrayed, and always in a subtle but critical tone. But all this is through the selective gaze of the two young persons in love, hence never is the film becoming dogmatic in its political sense.
A very good film, also with a beautiful photo. As a portrait of society this film is excellent. And please, don't confuse it with Ingmar Bergman's films. They are good in some respects, but this one is more "Swedish" than Bergman ever gets.
