This movie is one of my absolute favorites. It was one of these moments when I came across it by chance some night on German TV and couldn't believe the amazing discovery.
What drew me in most was the way the scenes work by just letting the audience observe, as an independent and even unnecessary third party, while the plot unfolds very naturally along the way. I would say that this very much reminded me of Jacques Tati movies. There is no doubt that we view a normal series of events and normal bevahior shown by the inhabitants of an urban landscape, as bizarre as it all may seem on second thought. In fact, the characters act very naturally, without anything "larger than life"; for example, when the main character at some point loses the key to her appartment, she seems unsure what to do, wanders about indecisively, eventually talking to the workers on the construction site where she believes she has lost it, then turning around, only to come back one day later because she could not get it out of her mind. Or when we watch her trying to lead her life in her apartment during the water shortage, stockpiling bottled water, and somewhat clumsily using the unusual form of water delivery to replace tap water.
Other characters in the movie happen to be a porn troupe, captured by the camera in exactly the unaffected (and, in this case, explicit) way as someone brushing their teeth with bottled water. Because the way of storytelling does not change, these scences work very well and didn't disturb me at all, except maybe the ending which shows probably less of a "normal" behavior.
One other thing that will prominently stay in your memory after you have seen the movie are the musical sequences that freshen up the piece and are not directly related to the plot, but incredibly colorful and cheesy (and also sport very bizarre costumes).
I found this movie very enjoyable and for me it's really an impeccable piece. Very much recommended.
