One must understand this film in the light of its background. In the 1970s the success of the sexual revolution in Europe had made things possible in mainstream film that perhaps would be frowned at today. David Hamilton was a photographer that made a name for himself with hyper-romantic images of mostly young teens. He developed a technique that involved copious amounts of vaseline on the lens to create a unique blurred effect. Out of this success the desire was born to translate his trademark style to film.
As basis for the film an older story about an innocent young girl discovering and exploring her sexuality was used, but the storyline is largely inconsequential since it merely serves as a framework for Hamilton's soft focus tableaux. The result is that the film feels a bit like pink cotton candy: overly sweet and insubstantial. That it still remains palatable is due to just the pretty images and the excellent musical score by Francis Lai.
