Better and cleaner than Mrs. Robinson, however the themes are disturbing and even illegal or criminal. In Canada, the age of consent is down to 14, and that behavior may be legal here, if none of those adults were in a position of authority.
However, the story is well acted, and appeared to be convincing as a drama. A well thought out story. It is not a porn type movie and only french kissing was really played, and there was no nudity at all in the movie. That being said, it is given a positive rating here, because it is a well-thought out drama involving a socio-sexual taboo. It's rated higher because it's a good movie for debate and discussion on sexuality as a whole, and the other features I stated above.
What really drives this movie is the socio-sexual taboo of a teenage boy and 40 year old women in romantic interactions. It is natural for a teenager to want to explore their sexuality - which makes them vulnerable to sexual predators - and perhaps this movie shows that these predators do not have to be a sick old male psycho going after a school girl, but could be any female. If it were a sex addicted 40 year old man going after a 15 year old school girl, this movie would have been banned.
