This 2001 film featuring Daniel Brühl, Jessica Schwarz, and Denis Moschitto is a romantic comedy about a young man who tries to win the attention and affection of a former high school classmate.
As far as I can tell, there is nothing particularly educational about this film. It may be relatable to some teenagers, but the examples of solutions here are not positive role models.
Much of this film centers around sex. Details of the warnings are spelled out well at IMDB.
