同班同學 (Lazy Hazy Crazy) (Blu-ray release 2015-12-28) is a Hong Kong movie about the friendship among three girls. Since they perform “compensated dating” (a form of prostitution) there are sex scenes. The odd thing with this movie is that it has several nude scenes even when the girls are not having sex. These scenes serve absolutely no purpose – they do not enhance the story and they are not sexy either. Were this movie done by a male director instead of a female one, I’d suspect they are done only to increase the screen time for nudity.
As for the friendship part of the story, its quality is very far below 閨密 (Girls) (2014). The friendship is shaky right from the start, collapses in no time when betrayals occur, and strangely is repaired in no time. Makes no sense. There is no point in watching the movie, not even for the sex scenes.
