This was the most pleasurable thing I've ever watched. The scenes were beautifully put together. The style changed from black and white to sepia to colourful, sometimes with a blueish tint, sometime with other colours. I loved the saccadic camera movements that matched certain sounds, e.g. a phone ringing. The actresses' styling (clothes, hair, makeup) was also beautiful. The music was very good (e.g. an epic battle kind of piece of music during the cake fight between the girls).
I liked the fact that the plot's point was to explore how the girls' reaction to the world's "badness" will end. But there were certain points that I didn't quite understand. I didn't really like how the girls sometimes spoke in a robotic manner, or how they seemed too naive and silly. Maybe that was the point: perfection isn't art anyway.
I appreciate the fact that the director (Vera Chytilova) made this film in a time when women didn't have the freedom they have today. One of the main themes in the film is women breaking the barriers of the society they live in, and the rules dictating their behaviour. It really is emblematic in that sense.
Overall I really enjoyed watching this film, but I didn't get where the plot was going, and where it actually went, plus the details I mentioned. But I would recommend it to anyone.
