Despite a decent cast and a few captivating moments in the last part, a return to the 2015 horror that too often lacks embodiment and stays on the surface, with the script lacking any ideas, thematics. Shame. The director was maybe afraid of hurting, of being indecent, of creating controversy with regard to the government perhaps, but the problem is that his film does not bring anything new compared to what we know. Through the medias of the time. What is the real point of describing this hunt for terrorists when we already know the events? Unfortunately, the script sounds pretty hollow. The big film on the subject with its possible implications (economic, political, etc.) remains to be made. Imagine what the Yves Boisset of the 1970s and early 80's could have done with this hot topic...
