Polisse 2011 is the greatest "fuck you" in the history of French cinema

Maïwenn Le Besco’s 2011 film Polisse tells a story about a “child protection unit” in French police. The film is written by Maïwenn based on real life cases that she researched with a real “child protection unit”. So the film has no bullshit in it. And yet given Maïwenn’s personal life, this begs the question: Was this movie secretly a hate letter to Luc Besson? Was this film the greatest “fuck you” in the history of French cinema?
