Thomas, the main actor, is probably the more a l'aise of them all. He's cool, hardy, and devious. A perfect (investigative) journalist :). Maybe he shows too much "holier than thou" attitude for somebody who blackmails and manipulates basically all the time to get his scoops. But well, at least he's sympa. Something "Florence (Daumal)" is definitely not... She's just too present, to "wanting to please everybody" to be a real character. My favourite is, by far, the fat rebel Michel Cayatte. Without him, this series would be nothing. He's a grouchy old timer, but the lines he's given would sound fatuous in a lesser actor. Like that, we almost wait for them :). On a personal level, I like her unlikely couple "Nadia/ Cylia Malki". Beautiful both physically and morally, who can't like a masculine camerawoman who falls for a man who could almost be her grandpa only because he's as cool as W. Burroughs :)? Caroline Ducey as the former hostage Marie Montheil made a much more remarkable role than, for instance, Florence, and with much less screen time. Oddly enough, her characters resembles a bit what happened with French/Colombian politician Ingrid Betancourt. "Life imitates art" :). Even without any makeup and after her gruesome experience, one can feel she's beautiful and exudes radiance. I just watched some pics of her other films thanks to IMDb, and am glad to confirm my hunch. Christine Boisson's character is pivotal, but maybe because she's not drawing attention all the time about her, it's only on second thoughts one remembers she was always there, showing good judgement. Albert Lehman is supposed to be the centre of everything, I would have liked Michel to play that role, but he says it very well on the last episode: "I like to complain, being the boss would be too difficult for me". Finally, Robert Plagnol plays a beau successful politician without much feelings. I knew him from some other TV series. Yes, the last episodes of the uneventful "Les Bleus" in which he plays ... a psychopath & rapist! Any resemblances between the two roles come by the reader of this review alone :). Sophie Kosinski is a character designed to be hated. I find she does what she is required, cold and efficient but not totally ruthlessly. So she's friends with Marion Cotillard... Good for her! Kaplan is also important, knowing it all but the end. Paul Guérin, in that respect, draws the upper hand from us all. I liked that Jacques Barlier didn't end in jail or something, like in bad movies as "Veronica Guerin".
In a nutshell, watch it!
