in the early 1970s and many of u who have embrace hippy or acid or alternative culture wholeheartedly and have realise that mainstream society be not go to change in the way we think it would . for me this film define the tension of now what . that many of the people i know felt at that time . do we head for the commune and create our own vision of utopia or do we radicalize and push for change . from the futile gesture to police and the radical rhetoric and the music of pink floyd and to the love making and the explosive image in the desert so much be in there . it capture well a significant moment in time .
