I was deeply bored by this however interesting film, a social drama, not a real pure crime flick although; a kind of Ed Mc Bain's novels atmosphere, the police procedural around a murder case, where Roschdy Zem could be a kind of Lieutnant Carella. I was bored because that's not my cup of tea. But that's ony a matter a taste. I prefered GARDE A VUE though. And POLISSE. There is here a tribute to LE CERCLE ROUGE with the lonely cop chaaracter living with a cat pet; remember Bourvil, in Jean Pierre Melville's masterpiece. And Lea Seydoux gives here another astotishing performance as a young lesbian, a kind of tribute of <hat she did in LA VIE D'ADELE, back in 2013. Good acting and directing, but not my kind of films.
