People who aren't "turned off" & disgusted by the current state of the world (enviromentally, politically, culturally, sociologically, etc.) will immediately understand this film and appreciate its beauty! Upon the first time seeing it, I felt it was unfocused and confused. The second time, when it occured to me that these people were living in front of the backdrop of something emotionally emasculating (random slaughtering, War, whatever you want to supplement), I realized what a masterpiece this film is. That uneasy feeling that life is unraveling all around you, that human beings are destroying each other, even though you don't directly see it...Bergman captures that feeling beautifully.
The interviews in the film bothered me for a while, but then I started to view them (and commend Bergman's brillance) as Brechtian distancing effects, as if Bergman is saying: "yes, live vicariously through these people, but after all they're just characters representing something, but they are NOT these people, so what???". Fantastic!
If you don't already own this and you love Bergman, what's wrong with you???
