my favorite movie

My favorite movie is "polisse". This is a French film, directed by Maïwenn, product in 2011. In this film, many celebrated people have a principal role as Joey Starr, Marina Fois and even the directrice, Maïwenn has a role.
This film tells the daily of the brigade to protect minors (BPM), this police department deals with abused and neglected children, juvenile pickpockets ... This is a dramatic film, but at the same time, it shows the relationship between colleagues, the discussions at lunch ...
This movie really touched me because the stories of some characters have really affected me (especially the scene with a little boy who is separated for his mother who lives in the street).
I like this movie because I am interested by this part of the police, she is essential for me, and we understand her role in watching the movie, but it took me some time to understand the sense of the end of the movie that's pretty weird (an actor commits suicide for no apparent reason).
